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 The price is very high
$500 for a pair of dumbbells is quite expensive. There are some good options in the same weight range available for less than $300.
Con The weight range is narrow
These dumbbells neither go very low nor very high in terms of weight. They won't work too well for people who are only getting started or those who are already very fit.
Con Only sold in pair
You can't get just one dumbbell, which would be cheaper.
Con They're not very durable
Some parts of the dumbbells is made out of plastic that would likely crack if you drop them on the floor.
