I purchased the thicker 5mm eKO mat by Manduka and I love it. I then purchased the light 3mm eKO mat to take to classes and I was very disappointed. I expected the mat to perform similar to the purple lite Manduka. Unfortunately, it didn't provide any support for my knees during poses. It is thinner than most "average" mats and actually provides less support. I was really disappointed. Lately, I've been using a studio mat under the 3mm eKO mat but I find it extremely frustrating and cumbersome. I've broken down and purchased another mat, the purple Manduka mat to take to class. I totally feel like I've wasted $40 on this purchase. I highly recommend the 5mm mat or the purple (lite) mat by Manduka, but not this one. It definitely missed the mark compared to other Manduka products. I gave it two stars because I don't slip.... 2 stars

I bought this mat from my yoga studio and liked the ecofriendly quality as well as the light weight compared to the other mats. However, this mat is so slippery that my hands and feet slide everywhere, even when the studio is not too hot. This weekend was so hot, I practiced on the wooden studio floor because I was afraid of injuring myself due to the mat turning into a slip and slide. I tried washing it at the recommendation of my instructor to no avail. Still slipping everywhere....I hate this mat and am looking to buy another one. 2 stars

Great mat, very sticky and stable, does not move on a floor at all.no smell neither :-) 4 stars

So far we are fairly happy with our new mat. It grips nicely and has a nice cushioning effect. Our only comment is that the natural rubber is a bit smelly, so the mat was consigned to the garage for a week or so lose it's scent. 4 stars

Manduka eKO 3mmYoga Mat
The yoga mat is exactly as described in the catalog. When you get it you will need to unroll it and let it breathe for a week at least. The rubber smell is very powerful. After it breathes, it is quite good and works very well. Not a lot of cushioning (if you need/want that) but a very good, non-slip surface for pilates or yoga. 4 stars
