I bought mine from Amazon in 2003 and it is still in amazingly good condition despite frequent use. I don't have any comparison as I've never needed another mat. I'm very pleased with the durability and performance of this product. So far it seems like it will last for a lifetime.

I do like the "stickiness" and cushion of this mat, but for the $12.99 I paid 2 years ago and combined for free Super saver shipping it very good, but for nearly 20 bucks it's average and not super impressive. I am 5'3" and find it just right for me.
I use it mostly at home but I took it to a highly regarded and priced class of a local yoga teacher and one of the first comments made to me was how narrow the width of my mat was =-/ Oh, well of course being small I had never really noticed because the mat is AVERAGE, but you may if you are taller and wider. For the current price plus burning fuels to get one I would recommend a local sports shop or general Dept. store.
If you need to find the "up" side the mat is engraved/moulded with the Wai Lana name and has a sticker on the correct side to use(I will upload). It also comes with instructions to wash off the residue from manufacturing(?) before use. If you have slipping problems try washing it as described- stick it in the tub with lukewarm water and a good rinsable, mild soap or detergant.

This is the best mat I've owned in a while. It's thick enough for pilates moves (especially ones that require balancing on our tail bones - eesh) and it's sturdy enough for yoga poses (no sliding around while doing a downward facing dog!). Not only that, but its pretty long, so I can use it for regular floor exercises too. Definitely worth the price.

Doesn't break the bank. I have bought three over the years and they are all from Wai Lana. Her workout, is a different thing. :-)

I have had my fare share of yoga mats and this one rates as one of the best. The thickness (1/8 inch) is just perfect - not too thick so it's easily portable but thick enough to provide adequate cushioning. What I really like about this mat is that it has the right amount of stickiness and grip, in a word, it is comfortable.
