Product arrive on time, was not damaged. We have had it for 2 weeks now... dumbells are already slipping around in the collars on the ends of the bars. The foam you use to secure the dumbell into the end of the bars is way too thin and not durable. We will try these for another week but i don't expect things to go better than they already have and we will most probably request a return. We like others, were looking for a way to expand out equipment (dumbells) without having to buy full on
