Not bad, better suited to archiving that nomadism

Transcend already have keys and adapters and relatively satisfied, is a recognized brand that is generally good products, I wanted to enjoy the specials of the brand.
The +
- Efficient reading (90 Mbit / s advertised on the packaging), it easily exceeds 100/110 Mbit / s v3
- Retractable (prevents the plugs that you lose). I did not have to worry about the mechanics to date, but it is possible that forces the system a little tired
- Tight Price

The -
- Winded write performance (25 Mbit / s advertised, which is already not huge for a v3), in practice between 10 and 20 turns
I've had this case on another Transcend key, it is not their strong point
- Too long (6 cm)
- LED under the blue cover over inconspicuous
- Building a little cheap (plastic trusts)

In short a good product all the same, then everything depends on the use we are.
Probably unsuited to too frequent coming and going in light of performance and retractable mechanism a little dubious, but more suitable for backups or archives more "static", the performance will be less important than the ability.
