Review: worth the price - these things are great. been using them for a while now and they are easy to use and compact for space saving. seem well made and not too rattly.
Review: Bowflex Selectech adjustable Kettlebell. - Amazing piece of kit - What a brilliant piece of kit not only because it’s very well made but being adjustable takes up virtually no space which is ideal for my home gym.

Excellent value for money as it’s equivalent to having 6 kettlebells.
