I purchased my AccuQuilt GO! cutter about 5 or 6 years ago. And, I LOVE it! I have never worn out a die, but have only cut 100s of a shape, not thousands. Today is the day to buy the cutter! They are $150 off!!! I have the GO! (Not GO! Baby) and they are usually $300. I got an email today saying they were on sale for $150. This does NOT happen very often! I think AccuQuilt offers free shipping, and your local dealer must honor the sale prices.
As someone else stated, you will have to replace your mat now and then. Supposedly the newer mats will last longer. Just don’t keep cutting your square in the same spot on the mat! I have even cut my mats in half so the cutter doesn’t cut on a portion of the mat that I am not using. You will understand that statement once you start running a die through your cutter.
Also, I cut 4 or 5 layers at a time, and I think AccuQuilt suggests 3 or 4. So, I push the limit. I don’t think that effects how long a die lasts, but more how long the cutter lasts. And, as I said, I have had mine for at least 5 years. Good luck and have fun!
