I'm a real Martelli fan. I bought one of their tables when I went to a quilt show the day after I found out that I was getting a large tax refund in 2012. It was the best quilting purchase I have ever made. Now when I go to quilt shows, I spend some time at the Martelli booth and help them sell their products. They all know me now. LOL!
The rotary cutters really do help with wrist/arm issues. Their videos are very useful in teaching you the proper way to use the cutters. If there is ever a problem with one of them, take it to the next show, and they will let you have another one at a deep discount.
If you sign up for their mailing list, and you will learn of their half-off sales.
