Main Clinic Supply review: Lifetime warrenty on simply go

Liked them until I disliked them. This Lifetime Warrenty - not really a warrenty and certainly not my life time. I purchased a Simply go years ago and it was replaced once, the second time it was out of warrenty so I purchased a lifetime warrenty and now that unit is bad, upon trying for a replacement I find they have none in stock and the unit is discontinued and I would put on a waiting list until one came in? I admit this unit I use as a backup (power outages, travel, etc) This is my choice not theirs, I paid their price for unit and lifetime warrenty and now have neither, oh yea! I'm on a waiting list. I'm 85 years old with about 50% lung capacity, lets see whose waiting list comes first. And last of all someone with no sense (me) purchased a ROVE 6 land guess from who I bought this (Mainclinicsupply) ;
