Since most Urethane Dumbbells are whitelabel from china anyway, I decided to take a gamble on a set of 5-100 straight from the source. The handles are almost 6 inches long which seem huge compared to a standard cap hex dumbbell. the grips are straight so microgainz fit perfectly with plenty of space and don't move. The knurling is about the same as a cap dumbbell, not terribly aggressive at all. They do require a bit of cleaning upon arrival since the QC is not what it would be if it went through rep or rogue. there are some light scuffs on the surface of some of the dumbbells and for that I'm going to take a quality star away, but honestly, for the price, they are very easy to ignore. Since they are urethane they don't have the usual used tire smell, but they do have the "I came directly from a factory floor" smell. I recommend giving them a day after cleaning to air out, I'm on day 4 and the stall mats have firmly re-established dominance. I spot checked dumbbells from 5 - 50 on a postal scale. each were above the listed weight, the highest discrepancy was 12 ounces on the 25 lb bell. I am very pleased with the accuracy (performance). This was a part of my second order with alibaba. make sure you ask questions, make sure you understanding the shipping side. I ordered using DDP shipping, that's where the seller assumes responsibility for all duties paid and getting it to your front door, most of the factories have a shipping broker they work with. make sure to request a lift gate and a pallet jack (mine had a motorized pallet jack this time and drove everything right into my shop). If you go through the link I posted, make sure to talk to Karen and let her know Patrick sent you.
