Very sturdy and I like the rubber pads for the openings for the dumbells. The slot where you stick your hand to pick up the weights is a little narrow and I have to use 3 fingers to pick up the weights. Luckily I'm not using it to store very heavy weights

A bit heavier than expected as I use lighter weight dumb bells. Assembled well and is definitely sturdy for my use. Slightly bigger than I thought it would be. Works well

The five level dumbbell rack from Fitness Republic did truly take only about 30 min. to assemble. No special tools needed; just the provided bolt driver and an adjustable crescent wrench from your household tool kit. The base was easy to assemble. The two vertical racks were a little more tricky, but no big deal. Provided instruction sheet was bare minimum, but it really didn't need to say much. Obviously, insert the bolt from outside to inner part of frame and place a washer between bolt head or nut and frame. With that said, I found that even though the rubbery, plasticky bumpers no longer stink to high heaven, they are apparently now stiffer (new material?) and difficult to install over the rack slot edges. So, I left them off. It's still a perfectly functional and dare I say, nice looking rack in our COVID forced home workout area. I don't think the bumpers are all that necessary anyway. I've got 20 lb. and 15 lb. dumbbells stacked next to each other with good room to spare. Just be careful when placing dumbbells onto the rack. There's bare metal to knock your fingers against.
UPDATE: I decided to work with the bumpers/collars some more and found that if you loosen up the slit opening by pulling it apart it will then somewhat easily slip over the metal collar. That should save a few fingers from pinching against bare metal. Updating to 5 stars.

Needs more space between weights. Nice and durable, easy to put together

So happy to find this without having to buy the weights too. Small enough to fit in the corner
