Lancelot Deluxe feedback wanted

Greetings to all fellow chastity enthusiasts! I’m looking for feedback from folks who are currently using the Lancelot Deluxe chastity device. I’m on the verge of buying one and would appreciate your insights regarding its effectiveness and suitability for long-term wear. Here are some specific points I’d like to know:

1. How suitable is this device for extended periods?
2. Did you experience any medical issues (such as sores, abrasions, or open wounds) while using it?
3. What was the comfort level of being locked inside?
4. How much “Give” did it have when your cock had a mind of its own?”
5. How critical is getting the right A-Ring size for a comfortable fit that prevents escape?
6. Did you ever feel one of your balls squeezing back through the A-Ring? Plus any other general information you might want to share. Thanks for sharing your thoughts!
