The nuobells have no problem changing from one weight to another. Just insert and turn the handle. thats it!
The trick to insert the lower weight dumbbell in between the plates is to use the dumbbell plate that you are holding, against the plates that is on the floor. Then you will be able to insert the whole dumbbell fully. I am sure the vendor have a video on how to do it because I share with them.
Shen is a great person to interact and understand about the product. Looking forward to my gains!!
Seems to be the only authorized distributor in Singapore. Highly recommend them for the great service, ordered morning and delivered before my dinner! Thumbs up.
