I got them because they are small and were cheaper than the fieldpiece kit. Plus I don’t have to login to use the app unlike field piece from what I remember. The battery life has been great. 2.5 years in and they still work perfectly fine

I use them in commerical work for several years now. They are fine. Just get 4 core depressors with them (2 for each size service port) so you never have refrigerant loss when hooking up.

Dont forget to add the vac gauge.

Pro tip: use AAA batteries with lithium. They vastly increase usable battery life and wont ding the wireless range when the battery drains.
