Effective
Anyone with a desk job should have one of these to fight forward shoulder posture. Great range of difficulty adjustment by choosing the number of springs to connect. Well made, nice knurling on the handles and the handles spin which help keep reps smooth.

Postage was a nightmare!
The product is great, but we’re travelling and courier companies don’t deliver to post offices. If we knew that at the start we would not of ordered. After three weeks we drove two hours to Bunbury to pick it up. We may as well have bought one there.

80s THUNDER. The pump is worth the premium price and the quality definitely matches.
