I bought the XL version a month ago and I love it!
At the beginning I thought I was cheating, I mean trading without learning difficult hotkeys on my keyboard but really, what is the point if you can send an order by pressing a single button?!!
I chose the 32 keys version because I like ALL my hotkeys on a single display without having to switch LONG/SHORT profiles, in case I am trading more than a stock at the same time.
I just sent them an email directly to clientservices and received a generic response about them having high volume and would get to my email as soon as possible.
Did you get one of these responses from your first email?
