Pros
Pro They are very durable
The dumbbells are made entirely from steel. They can easily survive being thrown on the ground.

Out of the box, the dumbbells can be adjusted from 5 to 45-pounds, but you can expand this range up to 120 pounds with extra add-ons with a total cost of $161.00.
Pro Lifetime warranty
If something happens with your dumbbells at any time, you can return them for a refund or get a replacement.
Pro Changing weights is quick
These dumbbells have a unique patented lock that lets you add or remove weights in under 15 seconds and then securely fasten them.
Pro The price is very competitive
Some dumbbells in the same weight range can cost as much as $500, so this is a great option if you're on a budget. Even more so, since you have the option to buy just one dumbbell for $150.
Pro They're very durable
These dumbbells are made entirely out of stainless steel, they will almost certainly last you long and survive being thrown to the ground without a problem.
Cons
Con They're very expensive
For some, such simple piece of fitness equipment as a pair dumbbells that costs nearly $400 (and above) may seem unreasonable. If you're only starting to work out you can easily find much more affordable options.
Con Only sold in pairs
You can't buy one dumbbell separately, which for some people is more convenient because it's cheaper and requires less space.
Con Weight range is comparatively narrow
For the same price, you could find dumbbells with a wider available weight range, say 5 - 50 or 10 - 70 lbs.
Con Short warranty coverage
The warranty only lasts for about half a year, when most dumbbell producers offer at least 1 full year of coverage.
