My two granddaughters (ages 7 & 8) love to quilt. I always had them stand right beside me and watch me when I used the rotary cutter. Now with the Slidelock they can easily do it with ME right beside them. Their little fingers are out of the way!!!! After using it for several months, I discovered it has as a wide width side and narrow width side. They use the wide side which puts their hand and fingers even farther away from the blades. Best tool I have ever bought and actually use daily. Yes, pricey - but, I have other gadgets that are sitting in my drawers.

I have 2, small and large, and use them all the time. I had problems with the ruler slipping also but not with this product. I have gotten my money's worth of use out of them for sure.

Love mine but wish they could put a few ruler markers on it. But I do think it's worth the money!

I did a shop hop this weekend and bought the Slide Lock, I have two of the Rule Steadys. I cannot see a bit of difference in using the Slide Lock compared to the Rule Steady. They both work perfectly on top of the ruler. I tried the Slide Lock butted up to the ruler and it worked fine. So it's just a matter of preference. If anyone else has both brands then they can post their opinion.
