cheapest adjustable dumbbells for sale

I'd like to start this review with a disclaimer. This is coming from someone who is mid P90X and has made great progress. I built up from regular screw on dumbbells to these. I'm not a body builder and I'm a beginner.

I originally looked at a few different weight sets. While looking I considered the following factors: Durability, convenience, versatility and space saving.

Durability: The majority of this weight set is made out of metal, mostly the important parts: the weights and weight adjustment part. The handle is a durable solid plastic and the other plastic parts are mostly just for show. Overall this weight set is durable and sturdy.

A decent set of adjustable dumbells with pros and cons

Pros

Takes up less space
The cost is much less
You can change the weights within about 15 seconds

Cons

They are bigger and a little bulkier than the traditional ones
The dumbells are in increments of 10 lbs unlike other reviews
You can't throw teh weights down
Somtimes the weights get stuck in the plastic holder

From all the reviews this one seems to be the best adjustable set on the market so far

I picked these up about a month ago and only wish I had bought them sooner.
This set is great for quick weight changes between workout moves. The system is stable and solid. I haven't had any problems with it at all.

The write up for these show a 10lb change between settings. To elaborate, each plate is 5 lbs. and you can adjust each side individually so you can change by a factor of 5. Just be aware, if you do, the weight won't be balanced.

I would definitely recommend these weights.
