I ordered a quantity of 25 and have a tight budget. I did not know what quality to expect... you get what you pay for. I expected that they would smell like cheap rubber and be a little cheesey, but its what I could afford right now. But I was pleasantly surprised to receive a very decent yoga mat at such a great price. No strong, funky smell. LoL The mat is "sticky" enough. I have not used them with students yet, to know how durable they will be. I travel to different schools, so I have yet to find out how they will hold up. But my job as a yoga teacher is to teach students to help take good care of the mats... I was not disappointed with the delivery. Oh, and delivery was very prompt. I think I received them within a week of ordering! Thank you and Namaste!
