USB Data Transfer Sync Charge Adapter Converter for PS

Pros:
price is very good the top jumps open when you press the release button so you can open it with one hand you can
attach the boxes one to another from each side the boxes material seems solid enough
Cons:
a little bit small for my needs (capacitors) the top release button is little so it has to be open with the fingernail
Other:
a good buy if you need to store small stuff like little computer screws, nails and many other small things
