The Einstein Collection Lock Puzzle - Tricky padlock brain game - 3D Brain Teaser Puzzles by Professor Puzzle

Bought as a Birthday gift for an adult relative - has had a number of outings but, as yet remains firmly intact and unsolved. It's fun and remains a work in progress for now. It arrived within a few days, is quite small but of sturdy build and extremely hard to solve - how to unlock it. Recommend Product and would use seller for further purchases

Absolutely love the detail of this lock, and appreciate the fluid moments of each individual moving part, well crafted and I’ll most certainly be acquiring the rest of thing fabulous collection.

Looks good, bought for a gift so I've not opened it

Amazing little puzzle had me for a few days !!

Beautiful Puzzle and well made.. Great for a beginner. I did this in a matter of minutes and feel due that fact its rather over priced. I would give this a 1 out 5 for its difficulty.Also as it was so easy I didnt realise I had completed it. I assumed the whole U comes off. It doesn't. Fun but over too quickly. I would price it T no more than £8.
