Query: I doubt it can hold 100 lbs.

Once I opened the package and assembled the unit I felt a sinking feeling in my gut that this is a poorly made product. The first thing I noticed is the rollers are no where near secure to the base. They wobble and twist with any weight to a corner. If you look at the enlarged picture you can kind of notice that there doesn't seem to be enough structual support to hold the rollers. After 2 days worth of use the clamping device stripped out. I took the device apart to see what the clamping nob screwed into - there was ony about 3/8 of an inch for it to secure itself. To make things more compliated the plastic cap on the bottom of the roller shaft fell off so I had to remove the plate on the base tube. Of course, when putting the base back on one of the screws stripped. To make a long story short, stay away from this product at all cost. The HTC HRT roller looks to be of better quality.
