I don't think so. I bought one this summer and I've only used it at my one retreat so far. But, I know I'm going to love it when I get back to my winter house. I didn't bring it back with me to the cabin. At the retreat I set it right next to my machine and I'm amazed at how often I used it while I was sewing. I didn't have to get up every time I needed to press a seam so it's going to save me a ton of steps. I suppose I won't be getting so many steps so that might not be good health wise.
I have heard of people saying that when the mats get wet they smell like wet wool (sheep) so I've decided to only use my iron dry. That's no change for me because all irons leak at some point so I don't put water in mine. If I need any moisture, I use Best Press or the home version of it.
I can't wait to hear how you like your new mat. Congrats!
