Whenever I've reached out to them, they've gone above and beyond to ensure that I have a positive experience. Of course, the only downside is the price point, which led me to deduct one star from my rating. While I understand the value of their products, I do wish that they were more affordable. In conclusion, Four Sigmatic's coffee has brought me so much joy and energy, and I highly recommend it to anyone in search of a high-quality brew. Thank you, Four Sigmatic, for making my mornings truly unforgettable.

Hidden taxes and duties making so expensive!

I can't help but echo the frustration expressed in this review for As a longtime customer, I have been a dedicated fan of the coffee offered by this brand. However, I too have recently encountered unexpected charges for taxes and duties on my monthly subscription deliveries. It's disheartening to have enjoyed a seamless experience for over a year, only to suddenly be faced with significantly increased expenses due to hidden fees. When reaching out to customer service, I was met with a similar response – the additional charges were attributed to the ordering process and deemed outside of the company's control. While I have cherished the product itself, the unexpected financial burden has left me contemplating the future of my subscription. It's my hope that this feedback encourages the brand to reevaluate their ordering process, as transparency and consistency are crucial for maintaining loyal customers. Despite these recent challenges, I am hopeful that will take this feedback to heart and work towards a more equitable solution for their valued customers.

Functional Creamer was ok

I was initially hesitant to try the Functional Creamer from after reading some mixed reviews. However, as someone who is committed to a keto lifestyle and intermittent fasting, I decided to give it a shot. When I received the product, I encountered the same clumping issue that other users mentioned. Despite this setback, I persisted and found that once I broke up the clumps, the creamer dissolved nicely into my coffee. While it didn't quite deliver on the promise of mimicking bulletproof coffee, I was pleasantly surprised by its effectiveness in helping me maintain my fast. Moreover, the lack of taste meant that I could enjoy my coffee as usual, without any artificial flavors interfering with my ritual. Although the recommended portion seemed minimal, I did find that using a larger amount made a noticeable difference. However, this also means that I've gone through the $30 canister faster than expected, and I'm not sure if the price aligns with the overall impact it had on my routine. In conclusion, the Functional Creamer served its purpose in supporting my fasting efforts, but the clumping issue and the fast depletion of the product make it unlikely for me to repurchase. While it may not have exceeded my expectations, I appreciate the role it played in my keto journey.

Transformative Fuel for the Keto Soul

My journey with's Functional Creamer was a mixed bag of surprises and disappointments. As a loyal follower of the keto diet, I was eager to enhance my morning routine with this creamer. Upon receiving the product, I encountered clumps that required manual intervention to create a smooth powder consistency. Although the promised transformation into bulletproof coffee fell short of expectations, the creamer did serve its purpose in supporting my fasting regimen. The tasteless nature of the creamer blended seamlessly with my coffee, making it imperceptible yet effective in extending my fasting window. While adhering to the recommended portions provided marginal benefits, increasing the dosage illuminated its presence in each sip. Despite its subtlety, the $30 investment introduced a fleeting sense of doubt regarding its long-term value. While the Functional Creamer may not have sparked a lasting flame in my keto journey, its temporary support in maintaining my fasting goals was commendable. As I near the end of my current canister, the decision to part ways with this product feels imminent. Reflecting on my experience, I acknowledge the functional yet transient role this creamer played in my daily ritual.

I am seriously unhappy with the service…

As an avid coffee lover, I strive to find high-quality products that not only satisfy my taste buds but also align with my values. When I discovered Four Sigmatic, I was eager to explore their offerings, hoping to find a brand that could elevate my coffee experience. I placed an order, anticipating a delightful trial. Upon receiving my package, I eagerly brewed a cup. However, it didn't quite resonate with my palate as I had hoped. Considering the price point, I decided not to pursue a subscription or future orders. To my dismay, I discovered that Four Sigmatic had charged my card and dispatched another shipment without my consent. Feeling perplexed and frustrated, I promptly reached out to their customer service, expressing my concerns. Their initial response left me dissatisfied, as they claimed I had a subscription that I unequivocally didn't authorize. Despite promising a refund and cancellation, I found myself entangled in a prolonged process with no resolution in sight. Navigating through a maze of unmet expectations and erroneous charges, my overall experience was disheartening. The lack of accountability and persistent marketing emails only added to my disappointment. In today's market, where integrity and customer-centric values should reign supreme, I regrettably cannot recommend Four Sigmatic based on my ordeal. Bearing the scars of this interaction, I will seek solace in brands that not only deliver superior products but also uphold transparency and ethical practices. To fellow discerning consumers, I advocate for mindful decisions when selecting brands to support, ensuring that every transaction embodies respect, authenticity, and integrity. Your experience, like mine, should reflect the essence of genuine care and respect for your choices as a consumer.

Turning Disappointment into Appreciation: My Honest Experience with

Let me share my journey with you. Initially, I was seriously unhappy with the service from It all started with a simple order of their coffee, a product that intrigued me. However, upon tasting it, I realized it wasn't quite to my liking, especially given its pricey nature. Things took a turn for the worse when, without my consent, Four Sigmatic charged my card for a second order just two weeks later. Confusion and frustration set in as I had never signed up for a subscription, and I was adamant about being cautious with my online purchases to avoid falling into such traps. Upon reaching out to their customer service, my concerns were met with a response explaining an unauthorized subscription linked to my account, one that I never knowingly agreed to. Promises were made to cancel the subscription and refund the mistakenly charged amount, yet these assurances remained unfulfilled, leaving me no choice but to involve my bank to rectify the situation. Despite these challenges, one thing that persisted was the relentless stream of promotional emails even after numerous attempts to unsubscribe. It felt like a constant reminder of a disappointing experience that I wished to put behind me. In retrospect, my interaction with left me disheartened and disillusioned.

The product is great, customer service less good

I recently had the pleasure of trying out products from, and I must say, the quality of their items truly impressed me. From the moment I opened my package, I could tell that their attention to detail and commitment to excellence were top-notch. However, I did encounter some challenges with their customer service that I believe need improvement. When I tried to reach out for assistance, I was directed to an automated phone system followed by a text service. Despite my best efforts, I found it difficult to get timely and satisfactory support. I believe that with a more responsive and hands-on approach to customer service, Foursigmatic could elevate their brand to even greater heights. I understand the importance of streamlined communication and flexibility, especially for those of us with busy schedules and specific needs. Overall, I believe in the potential of Foursigmatic's products and hope that they will address these customer service issues. Despite my experience, I remain a fan of their offerings and look forward to their future advancements in both product quality and customer care.

Unparalleled Quality, Mixed Signals: A Honest Review of Foursigmatic

Embarking on my journey with Foursigmatic, I was instantly captivated by the exceptional quality of their products. From the tantalizing flavors to the holistic benefits, each sip was a bouquet of wellness and delight. However, as I delved deeper, the experience soured with their customer service. Navigating their automated phone system felt like being lost in a labyrinth, only to be guided to a text service that held the promise of assistance. Yet, the response - a virtual shrug stating absence until the elusive window of Mon-Fri, 9am-5pm - left me stranded in a sea of unanswered queries on a Wednesday morning. An absence of expedited shipping options further tested my patience, hinting at a rigid structure that failed to accommodate the urgency of modern life. It was a bittersweet realization that amidst the unparalleled product quality lay a void of flexibility and efficient communication. While the allure of their products beckons, the yearning for a seamless customer experience lingers. Foursigmatic, your offerings are exceptional, but a touch of responsiveness and adaptability would elevate the journey from great to extraordinary.
