Keyholder’s Guide: QIUI Cellmate VS Remote Chastity Lock

I have used 2 ways to realize remote key holding chastity training for my slaves.
1 Use QIUI Cellmate- an app controlled chastity device
Only very few slaves choose this option as this chastity device looks quite bulky and it has very limited size options.It sells for about $189-$279, which is not cheap.

2 Use a remote accessible lock (I and most of my slaves prefer this way)
The price for the lock is about $20~$40, which is very cost-effective, much cheaper than Cellmate. The lock is usually very big so it’s not feasible to lock your chastity with it. You need to put chastity keys in a box and lock the box with this big lock!
