Query Regarding the Cellmate Device

Hello all, I’m fairly new to the world of chastity and am currently unbound after my time with a keyholder came to an end. I found out about the app-controlled Cellmate device and thought it might be a solid option for keeping myself locked up. That said, I’ve noticed reports of some security concerns and other issues. It’s also quite pricey compared to alternatives, so I’m curious: would someone who has used the Cellmate recommend it? Are there any downsides worth knowing about before investing in it? Thanks ahead of time!
