The full Posture Trainer with all options (including chastity belt) weighs about 11 kilos! We have to suspend it from the ceiling to lock a girl in it! The awesomely gorgeous Birdy Dee from Scotland wanted to give it a go! It is the heaviest and most rigid device we have, but Birdy sure loves a challenge! Sure enough, after locking her into this device and removing the support chain, she soon wanted to get out. "It's so heavy!", she moaned. Aw, poor Birdy! We gave her the many keys and tools necesarry to unlock this device, just to see her struggle even more. no chance of escape!
