Rocketlok 100-Pound Adjustable Dumbbells (Pack of 2)

Their customer service is first rate but the product is not in my opinion. I really wanted to like these but found, after a short period of use, the locking mechanism to be problematic. I replaced one of the plates through the company with no issues at all...very good service! Soon however,found other plates unable to lock, unable to unlock, etc... Possibly if the securing feature was made out of something other than plastic? Maybe I was just unlucky with this particular set but I did return them. I do think the "idea of them" is really good.

The locking mechanism seems to work great but I ordered two of them. When they showed up at my house they were both broken at the handle. BOTH of them. If I were going to make a dumbbell, the handle would probably be the strongest part but what do I know. So, if you buy it, treat it gently.

The first shipment was damaged in transit, but Amazon took care of sending a replacement set immediatley. I had also contacted the manufacturer, they responded quickly and were very helpful.The product is of high quality, and works just as advertised. The adjustment of the weights is quickly and easily done. The length and diameter makes them easy to use and not at all bulky or out of balance.. I'd most definitley recommend purchasing this set.

Would not recommend buying these. Received first ones broken, Second shippement they were broken as well. Returned for my credit

I love my new dumbbells they are not perfect but they are easy to change and have the option to combine more weight that the other dumbbells options. I bought two stand for easy access of each side were I exercise. I recommend this product.

These work great and are very easy to adjust!

These are really compact and work great. My wife even loves them to. My friends always comment on how nice they look in my living room. I checked their web site and a really cool adjustable kettlebell is coming soon from Rocketlok and I cant wait to get it.
