I liked it well enough until keycaps started sticking to my fingers and falling out while I was typing. I think the overheating weakens the tiny and fragile plastic hooks. Also, some keys get stuck or repeat letters but I got used to it.
If it is a 200€ laptop, I might be okay with this. But paying 2800€ (15" model, least expensive configuration) and then not being able to work because the keyboard falls apart … unforgivable. Let’s hope Apple introduces a more reliable Pro laptop next year. Until then I have to plug along on my 2014 model.
