## Description

MillSTEPS Breathing Exercise Device for Lungs,Lung Expansion & Mu-cus Relief Device (Blue) : desertcart.co.uk: Health & Personal Care

Review: Highly effective, inexpensive, great little gizmo. - This is a fantastic oscillating lung exerciser that is sooo much easier to use than the Airphysio - and at a fifth of the price. No faffing about trying to find an elusive 'sweet spot' to get the darn ball oscillating, and robust in its twist-off, perforated cap, so I won't have to reinforce the mechanism that closes it with epoxy resin to stop it falling apart. I've been using the Airphysio device for months and whilst it effected an improvement, I still find it infuriating to get into the exact position, with the pipe thing at exactly the right angle and with exactly the right pressure of exhalation for the darn ball to oscillate. This Opep device worked immediately, no faff, obvious oscillation, so much so that with the same weight ball as the other thing, I got light headed and needed to adjust it. This is worth it. It says it should last 6 months but it looks and feels far more robust than the very expensive version, that cracked and broke within a few weeks. Highly recommended.
Review: Breathing godsend device - I suffer with a condition called chairi malformation type1 and have had 2 decompression surgeries on my brain and surgery on my spine. I constantly get a really large build of phelgm in my throat and on my chest. Since using this i can honestly say that the problem has cleared up about 96%. It really is a godsend. I am able to breathe so much better and do not struggle as much as i used to.
