Hi, I have 8 wireless tags and they use CR2032 batteries… I’ve been using them for more than a year now. The batteries last somewhere from 3-6 months depending on their configuration (long range or not).
The only drawback is that they need yet another hub. The ST integration is working well.
I really like their small form factor, and the number of features they bring in a small package.
However, please be aware that support is not always there to help in case of problems. I think that the company behind them is sort of a one-guy operation.
