I've had the Go as soon as it was available to buy. I love it. The problem some had with the dies was mostly human error but there was a problem with one of the bigger dies and AccuQuilt replaced the defective die that some did get. The main thing to remember is order from a AccuQuilt dealer. One that can replace or return without a hassle. The cost now is way less than what I paid and I would buy it again at the higher price. It's worth it to me. The Go is a personal model and won't cut but four layers accurately, the Studio is for ten or more layers and best for mass cuttings. I love sewing my scraps together and then cutting out a shape and have it all scrappy and cut perfectly. The tumbler die is great for this. I was amazed at the amount of yardage I was tossing in the scrap box. I ordered a few more dies for Christmas for a gift to myself. I always buy myself a gift. :-D
