I see still 2 defects:
- Readers are quite noisy as it has been said by other reviewers. I sometimes use these drives at night in my room and it really is a bit annoying.
- The mounting kit for headrests is a plastic that looks very fragile and could be in case of breakage of sharp pieces. This is not very reassuring. It's just a priori, I have not had any real experience of this type at the moment but I have the product for 3 weeks.
