Well it's not mecanique who do it... it seems they only do the IDE, the same as Melabs, Proton ones.

Also, their Purchase link didn't work when i tried and seems to be a really new-kid-on-the-block one. The device support list is limited to the 18F serie.

How good it is? I don't know... who knows? There's no post on their forum. Is this so good that nobody have problem ... LMAO!

i wasn't aware of that one and only by having a look at their forum, it seems i'm not the only one

Why not trying the demo and post your comments here?
