I like this bag. Good quality, nice color. Looks the same as on the pic. We didn't travel a lot but sometimes it happens :) it has a lot of packets, what is great. I like it.

I've used this on a number of projects: taking a car dealer's name off the trunk lid of my car, getting the sticky residue off a window where weatherstripping had been, cleaning a stove. The only place it fell short was cleaning excess caulk from around a sink. It worked no better than plain water.

This is great for the beginning stepper. Sturdy and easy to adjust height. My only word of caution is that it is smaller than expected. On the upside, that makes it easy to store out of the way. But I wear a size 7 1/2 shoe and my feet fit just right. I would be nervous if my feet were much bigger. Overall I am very happy with this purchase.
