Product description

The new TwistLock Adjustable Dummbells are the most space efficient and easy-to-use option available today – in fact no other adjustable dumbbell weight can be changed as quickly and easily as the TwistLock dumbbell! With a weight range starting at just 5 lbs, this gives users of all fitness levels the opportunity to execute a wide range of exercises in the comfort of their own home without having to purchase the equivalent number of regular dumbbells. No knobs to turn, pins to align, or levers to slide – just twist and go! The patented TwistLock cutting-edge technology allows quick and easy weight adjustments with the simple twist of each dumbbell handle. You never have to take your hands off the dumbbell handles – simply place them into the dumbbell cradle and twist the handle…once the desired weight is shown in the readout window, you are ready to go! For added safety, the TwistLock weight adjust system can only be made when the dumbbell is docked with the beautifully designed cradles (included) that hold the dumbbells. Nobody wants oversized, bulky, odd shaped dumbbells getting in the way of your training. That is why the StairMaster engineers and designers spent so much time analyzing gym quality, commercial style dumbbells – after all, that’s what you would prefer to workout with in your own home if you had the space and money to buy them. They made sure the TwistLock design looked like a dumbbell, felt like a dumbbell and delivered results like a dumbbell. Unlike many other adjustable style dumbbells on the market, the perfectly balanced TwistLock dumbbell delivers the same basic sizes as gym style dumbbells as you increase the weight…so whether you are using a 5 lbs or 50 lbs weight, the size of the dumbbell closely resembles the size of the same weight you would use in the gym. The contoured and textured dumbbell handles provide a comfortable and secure grip during your workouts.

1.0 out of 5 stars False Information on this product, Do not buy before reading this.
Reviewed in Canada on November 25, 2016
All the information on this page is not accurate at all, the pictures do not reflect the real product.

Few things to have in mind

1) These are not 50lb each, nor are in lb.
2) Each Dumbell is 20kg and they go like this 2, 4, 6,8,10,12,14,16,18,20.
3) The mechanism in the picture shows metal component in the bar that crosses all the weight plates ( this is resposnible to carring the plates) the ones I got they are plastic. ( I dont know how long they will last)
4) No assembly instructions :( (is not that hard to fugire it out but still is a miss)
5) The price of these pair is always changing , I first saw the for less that $400.00 3 months ago. I pay (four hundread and fifty nine and I got 50 off becuase I complained about the real weight. )
6) Very suspreise that they know about this mistake and they have not change the information.

When usisng the dumebells you have to be carefull and make sure only grabs the plates that are needed, for this set, sometimes when you go from 6kg to 4kg it will not release one of the plates and some times it will get stuck or fell.

UPDATE!!!!! One of the handles is broken, it won't turn anymore, so you are not able to use it. I have contact 3 times the company selling these, so far nothing. DO NOT BUY THESE BAD MATERIALS Cheap quality.
