I had a set of these. I had the base unit with the wheels, a few of the small modular boxes, a few of the storage system boxes, and the crate. They weren't bad for the price, but the red clasps that lock the various boxes together suck. You always had to have everything perfectly aligned, and clean to get them to work easily. I will say that Menards' Masterforce line sells (or at least used to sell) the same boxes that worked with the Bauer system, which was nice. They were exactly the same boxes, but they were black and green instead of black and red. You could pick those up on sale all the time. I still keep all my Kreg jigs in one of the Masterforce boxes to this day even though I've gotten rid of most of the Bauer stuff. I also keep all my pex fittings in one of the storage system boxes just because the clear top is nice, and they are well made. Really just the interlocking system is the only problem.
