I have owned all types of adjustable dumbbell ( Bowflex, Core Home Fitness, Snode) and I can honestly say my Nuobell 80 lb set is by far my "Go-To" set for convenience, quick change of weights and durability. Snode is more durable but it doesn't come in 5 lb increments and it is a hassle to use the magnetic attachments (platemate). After using my Neobell for > month, I am confident of the build quality to state I believe the dumbbell will probably last > 10 yrs if I don't drop the weights. Fantastic product!
The reason I give a mixed review is that I pre-ordered my weights in Feb and received them 4 months later! This still might be acceptable to me ( but maybe not to others) because : 1) I love this product 2) I did an exhaustive comparison shopping - this was the lowest price on the market for a brand new Nuobell if you required shipping 3) Purchased from an authorized dealer and 4) "Alex" form customer service was great. She constantly kept me informed of my shipment even as it got delayed multiple times and she even personally called me on the phone to update me of my shipment. She is an Angel.
