It's a very good quality, easy to fold (Lifehack for me is to make a triangle and keep toys inside, if needed).
It is thin, but ok for little falls (now learning crawling), warm, beautiful. Easy to wash in the shower. Has two sides with different drawings - for different moods.
Big enough. but if it doesn't fit - I use part of it as a wall. this what you cannot do with a puzzle ones.

Negative-a bit expensive (I bought it we with an offer for 50 eur)
maybe a bit too thin for the future falls when the baby start walking. But still better than a stone floor.

And yes, as said in other ones reviews - it us not exactly 150x200. It is 147x196 and a bit less than 1 cm thick. But I understand this is happening with all such products from all companies, they are rounding the measures.. So I was not much surprised.
