excellent portable concentrator, could be just a little lighter. The strap slides off my shoulder even though I have tried numerous fixes to stop it.

Gen 4 on standby in car for portability and Gen 5 for home or lengthy travel.

I ordered this portable device for my sister. She doesn't use it very often, but when she does need it, it's the best. It's compact size and rechargeable battery are just what the doctor ordered (pardon the pun)!
