Question: how long are the bars?
Document: These are a good bargain. Go to your local sports store and pick up a few extra bars and you're all set up.
The bars are a much better quality, and the surface provides a good grip, and the fasteners spin on and off smoothly.A good selection of different weights and of course the amount you get make this a great deal.
I just got the 100 lbs dumbbell today. It's pretty awesome. Came in two separate boxes. One box contains the 4x10 lbs plates and the other contains the bar, spin locks, 2x2.5 lbs, 2x5lbs, and 4x10 lbs  plates. The bar is about 19 inches long and the diameter of the bar is roughly 1 inch.I used it today and everything was peachy but the black paint does flake a lot leaving a lot of black paint chips all over one's hands.
chrome plating is peeling off at the edges, leavving pieces of chrome chips embedded in my carpet. besides that, weights are good.
awesome set of dumbbells thanks a million! with my bench, I will make sure these dumbbells give me the workout I desire. James
These weights get the job done. They are a pain to switch out for more or less weight, but they work. My biggest complaint is the chrome plating, which flakes off of these weights; I would suggest getting the plain black ones, without the chrome. Also, inspect the set for metal shards, I got a deep metal sliver in my finger that hurt like hell, and bled all over the place. These are cheap weights, but they serve their purpose.
The weights shipped fast, I received them after only a few days, much faster than I had expected to receive them. Like most people here have said, they're weights, they're just blocks of metal meant to be heavy, it's pretty hard to screw it up.Personally I didn't notice any odd smell on mine. I saw some other people complaining about that so, naturally, the first thing I did when I opened the package was put my nose right up to the weights and smell.
The &#34;chrome&#34; is a metallic coating on the outside of the weights and flakes of it come off. I would have rather them just be the base metal than have these little spliters of chrome foil.Note: this is pretty minor, and for the most part the chrome has remained on and looks good.I don't think there is a better deal you can get for the weights, and that is even comparing to used ones from craigslist.
Pros:-Made of metal-Heavy-Fit together-Decent priceCons:-Paint sort of chips off on my hands. Not really that noticeable, though.-Had to pick them up myself, above weight limit for my area.
