Novices and newbies discussion

I’m fairly new to this. I own a Masters Series SL101, which is a nice stainless steel piece that’s reasonably comfortable but quite heavy. To manage the weight while locked up, I typically wear jockstraps or pouch-style underwear. The main issue for me is my wife finds unlocking it tedious — locating the key or retrieving it from her necklace, then getting it into the lock properly can be a struggle. Plus, when she decides to let me out, she wants it done quickly. So I was thrilled to discover a TSA-approved luggage-style lock that uses Bluetooth technology. The Dog & Bone model is small and light enough for use with a chastity device! My wife loves gadgets, so this works via fingerprint recognition on her smartphone, unlocking from across the room. Even better, if we’re apart by two states, she can grant my iPhone one-time permission to unlock it remotely and receive a report confirming exactly when that happened. The catch is that between the weight of my device and the lock, using my Masters Series unit isn’t very practical. However, if I find a lightweight yet comfortable alternative, the possibilities are endless. I did purchase an affordable metal device with two small posts that slide into the main ring on either side of the locking post. Unfortunately, those little posts popped out during an erection and pinched me terribly! Does anyone have good recommendations for a comfortable, light locked device? I’m willing to spend up to $100, but not hundreds of dollars. Thanks in advance. I’d be happy to update everyone on how the Bluetooth lock works with a chastity cage.
