Anova Culinary Sous Vide Precision Cooker Pro

First off, I concur with the other reviews claiming that Anova’s customer support is non-responsive AND I have 3 different Anova Precision cookers, all of which have been defective. I purchased the Anova Precision Cooker Pro. After reading the multiple reviews of a problematic Pro after updating the firmware, I decided to attempt use before performing the firmware update. After placing the Pro in a vessel of water, I powered the unit up. The “Soft” buttons all appear to function aside from the Start/Stop button. The Pro was problematic getting connected via Bluetooth, but after a few attempts, the Pro connected to my phone. I was then able to quickly connect to my home Wi-Fi. From the app, I was able to initiate a cook from one of the recipes as well as Start/Stop the Pro. Still unable to Start/Stop the Pro via the button on the unit, hoping that the firmware update would alleviate this issue. After a one hour cook at 176 F, the Pro would no longer heat water, regardless of the temperature setting. After updating the firmware, the Pro Start/Stop button still does not work and still does not heat up the water. This Anova Precision Cooker Pro failed in 1 night. I also have a Anova Precision Cooker Nano which I received, new, as a gift. While it took a noticeable amount of time to heat up and did not have Wi-Fi, in comparison with the Anova Precision Cooker, the Nano worked fine for just under 6 months. At just under the 6-month mark, we began getting the add water indication with the water up to the Max line. When the add water notification goes off, the unit stops heating and circulating…AKA stops cooking. After soaking the Nano in a 50/50 water/vinegar mix, the Nano would once again circulate and heat. After unplugging the Nano and replacing the 50/50 water/vinegar mix with water, I plugged the Nano back in to find that the Nano would no longer power up. Yes, I attempted plugging the Nano in different outlets. I started my Anova relationship with the Anova Precision Cooker. I received this as a Christmas gift in 2018. I had 3 years of mostly reliable service out of the Anova Precision Cooker. The issue that began at around the 2.5-year mark, the removable stainless-steel sleeve began to be loose when installed. At around the 2.75-year mark, the clamp broke at the water vessel clamping area, but I was able to glue the clamp back together. At the 3-year mark, the plastic case of the Anova Precision Cooker, where the stainless-steel sleeve connects to the unit, broke in multiple pieces. I assume this is from multiple rounds of high heat. These were the only issues that I had with my Anova Precision Cooker, and to this day, the unit works…just with no stainless-steel sleeve. The Pro appeared to have corrected the issue with the stainless-steel sleeve, that I encountered with the Anova Precision Cooker, by extending the connection area up higher on the unit, assumable farther away from the heat source. Unfortunately, the Pro that I purchased new did not function longer than 1 hour. Because of the reliability that I had with the Anova Precision Cooker and contrary to the premature death of the Anova Precision Cooker Nano, I decided to roll the dice on purchasing the Anova Precision Cooker Pro…even after seeing the multiple negative reviews. Unfortunately, my Anova Precision Cooker Pro was a lemon, AND I have received no response from Anova regarding the issues. I hate to say it, but “BUYER BEWARE!!” The pic is to show the 3 defective units, side by side. Anova, you need to have a serious look into your quality department.
