Final Verdict and Review

In my opinion, Giantex 66 LB Adjustable Dumbbells are one of the best adjustable dumbbells present in the world. As, the competition of adjustable dumbbells regarding special features is on increase day by day but still Giantex adjustable dumbbells provides great factors of cheapness, durability and vast variety of weight set which makes them a necessity to be in your home as well as fitness gyms. It’s a pretty obvious thing if you are getting a set of adjustable dumbbells which is providing you super cool basic factors so there would be a lack of some special features as well. Like in my experience, the quality of Rubber washers and Screw caps was very cheap and there was a frequent issue with falling of rubber while changing weight. Though you are been provided with extra Rubber washers but why not give only a good quality of rubber at first place then providing cheap ones with quantity? Also it requires time to change them.

As mentioned on product specifications and features you are been provided with secure fit collars but in my experience the collars are not really that secure fit. There is a wobbling of weight after several reputations and the collars need to be re-tightened. Since, this is not really a massive problem if you are looking to its factors and price tag it’s just a very rare issue I faced. The length of the bar is very awkwardly long as far as I’m concerned. I know the manufactures have done this to adjust all the plates if you are requiring 100 lbs. or more but it makes the exercise very difficult when you are going with few plates. Like when I use to perform an exercise of shoulders, there was a clanging of both the dumbbells in few reps which made my form to go worst and ruined my consistency very much. This is a very important issue I faced. Overall, purchasing Giantex 66lbs. Adjustable dumbbells Reviews 2018 will be a good choice to save home or gym budget. But if you still have the budget to get access of more features then you should probably look for any other adjustable dumbbells like Bowflex.
