I've been out of DDR for a while. I still have a Cobalt Flux at my parents home. That seemed to hit the perfect sweet spot of size, weight, and durability, I've literally had it for a decade. How does this compare?
I've never used one myself, just going off what the internet says about them. There are lots of reviews of them on YouTube (people either call them "l-tek" or "polish pads")
I ended up with the L-Tek one you linked. The buttons seemed awfully futzy to me, and she says they're ok but not great - plus her toes hit against the edges of the raised non-button squares and hurt.
