Major design defect

I pass on what has already been said.
I confirm that the interface is rather odd from so much so that I wondered if I was not on my old board.
But perseverance is really nickel and difficult to envisage another.
Ergonomics is actually very good and macro management software is certainly the most powerful of the market.
With the ability to manage the primer sequence, the repeat sequence and the terminal sequence in separate ... more.

In short everything is idyllic without this defect.

A weakness in a button under the thumb (the top left)
The holding tab is too fragile and forcing it breaks.
Do not wonder if your default concerns, it is present and if you use this button it will come to break.
I am in my 3rd and there I decided not to program it.

Damage still not be able to use all the buttons for a MMO mouse!

I put 1 star for two reasons.
- This fault
- And after sales service of DEPLORABLE MADCATZ to France which began nearly 2.5 months before solve nothing at all! to thank you for taking the AMAZON relay and help me in 3 days
