Review: Didn't Last - Item worked great for nearly two years then just quit. No display, no nothing! Giving it a good rating only because when it worked out was great and they didn't have a rating for longevity.
Review: App is a Joke - You are Paying Double for no benefit - My suggestion to anyone reading this is to pay 50% as much and just get the local readout (Non-WiFi) type of device as the app and WiFi on this unit are, in all seriousness, a joke. You cannot adjust "Heating Differential" or "Cooling Differential" values in the BN-Link Smart app. You can only adjust these values locally by pressing buttons on the control unit itself. If you do not set these differential values then you should know that your minimum and maximum values then control when either the heating or cooling elements will turn on. It will yield huge temperature swings so be prepared. Please also know that the values shown on the app only update every 4 to 5 minutes. Yes, I used a stopwatch while standing there holding my iphone and looking at the local controller. Temp moving up a tenth of a degree every few seconds on the controller, but the value on my iphone in the BN-Link Smart app only updated every 4 to 5 minutes! And equally annoying is that even though you may set 80.0 F as a value in the app, as soon as you hit the save button the main screen will show 79.9 F. If you then try 80.1 F as a value in the app, as soon as you hit the save button it will display 80.1 F !! Incredible for what you are paying to get a remote WiFi benefit when in reality it simply doesn't deliver.

### ⭐⭐⭐⭐⭐ Good product, easy to use and has the 15 amp capacity I needed
*by T***D on June 8, 2025*

Works great and has the 15 amp capacity I needed. It works just like the Inkbird but the Inkbird only has a 10amp capacity and I went through 4 Inkbirds which all failed until I came across this product.
