Conditioning belts for belt sander

I have a 1x42 Delta (sanding) belt sander. I didn't realize these abrasive belts were available, kind of like scuff pads which I use all the time. They don't indicate a maximum SFPM. I think the belt thickness should be OK. They say for use on wood & steel (not sure why not aluminum which I do all the time as long as you keep them separate). Anyway, I think they would be quite useful. Anybody using them?

I tried some Red Label brand on my HF 1 x 30 but they rubbed against the guard so I returned them. I've since picked up some 3M Scotch-Brite 10mm x 330mm belts for my mini-belt sander which work very well for small deburring jobs. The 3M belts are not as thick/bulky as the Red Label ones, so may work better on all machines than the Red Label brand.
 
I've tried them. They do not produce a "flat" surface on the work. The edges are always rounded. Ok for some work I suppose, like cleaning or scale removal, and they don't last very long.
IIRC the tape joint broke after some light use so it was used for sanding on the lathe after that.

Yes, that's what I need to check too just eyeballing the thickness.

@Arbutus Yes they are more for blending & surface texturing. There is a possibility of losing dimensional control. Kind of a niche tool. I have a Milwaukee 3/8 band cordless band sander with an assortment of these belts & they work great. Maybe a 1x42 is more of niche item, nice to have vs need to have. I can see the increased probability of snatch & launch too. The Milwaukee has variable speed.

The belts I have are made for band sanders, and my mini sander is low power:
