Cheap scrap dumbbells

I am unfortunately fallen for this free weights, though is, as I have just read, plastic dumbbell while, but I'm pretty sure that that was not there was when I bought myself, for the weight plates actually consist of the cheapest plastic, the is processed lousy, so one of the discs, where the filling plug is, was torn down and a strange sand mixture expired.
But what annoys me even more is the enormous size of the disks, yielding some exercises can not perform properly when compared to cast-iron discs.

Likewise, the star turn locks on easily, so you must always follow this. This is in my view the fact that more power is available due to the enormous size of the slices for a rotation of the discs on the barbell, whereby the closure can untwist itself.

The barbell is fine, but that's really the only piece on this scrap product which has satisfied me.

Return falls due to high shipping costs also, because I'll keep the scrap instead prefer me to make a head drum.

So: do not buy you these dumbbells unless you want sand for your pond / sandpit ... quite expensive sand.
