First thing to check is whether your drives are ⊗⊗⊗⊗. There is a trend among Chinese suppliers to sell you ⊗⊗⊗⊗ drives. Such as they sell you an 8 GB drive, but it's only 4 GB, it just reports it is 8 GB. Thus when you store data on it, only 4 GB are stored, the other 4 GB are lost. If you want ⊗⊗⊗⊗ drives, there is a way to make your cheaper and smaller real drives into ⊗⊗⊗⊗ once.
This particular condition earns you an automatic neg, and a call to credit card company. Although many buyers don't find out about this well after 90 days of use.
There is a reason everyone of us is banned, selling a product such as a ⊗⊗⊗⊗ USB is a good enough reason, IMO, of course. Because we are dealing with precious computer data. Imagine uploading your taxes on a drive, just to later find out half of it is lost.
Second thing. I would not lay my hands on a USB that looks like a lego. Period. I'd go for something more slick, like a black compact looking box, or perhaps a wood shaped art. Now this is of course subjective, there are people who buy space shoes to compliment their space wind breaker. Point is, a lego shaped USB stick is far from a winning idea.
