22 Litre and Inhaler Cup

My husband started using Evolve Oxygen following chemo and radiotherapy. We have found the product to be of great quality and makes a difference to how he feels physically and probably psychologically. It makes a difference to have some puffs if feeling tired and after exercise. The inhaler cup is a good design for ease of use and feels like you are taking in the complete volume of 02. The trigger release is a good size and is simple to use for my husband who has left sided weakness. Super quick delivery, well packaged and can be recycled in the home recycling collection. Recent customer service involvement with the MD and matter resolved within less than an hour of contacting Evolve via Amazon. Excellent customer care! Would highly recommend Evolve!

it was a good product but it's a bit too powerful for my Lungs, So I had to get the 1 with a different top but the same product thank you

It works. Not sure why my oxygen levels are always low, but a few deep breaths of this & the levels go up quite a lot, eg, from 88 to 96... I'm definitely aiming to get it up to 100 again. Very easy to use once you get the hang of it, & is definitely lasting quite a lot longer than other brands - I'm impressed.

I thought I'd give it a try to boost my dwindling SPO levels from OSA. It does seems to help keep my levels up. I'd read that it runs out fast, but I just use a couple of inhalation and hold my breath for a bit and it's lasting very well.

good product, lousy customer service

I have these in due to breathlessness and fatigue very useful and do the job obviously not a replacement for hospital type but helps me they come packed well I only ever had one lot that was empty but Amazon quickly sent out new so all good transportable accessible size is ok for travel easy to use better than the masks I always have these in

Packaged with care. Wonderful product, mask/ mouth piece fit securely. Definitely be on repeat buy.

Excellent
