Bests & Worsts Reviews from Amazon

I ordered my NITRO "sold and shipped by Amazon". That's always the best way to go for a hassle free return policy. I did quite a bit of research and decided on the "DRIVE" mainly because of my height. So tall guys, rest assured this one is a great choice. ( I'm 6'2" ) Also...…..and this is important****** read the entire description of the others you may be interested in. I noticed quite a few with "fine print" hidden somewhere on the page that says the other brand you are looking at "may/is too wide to fit through standard door openings. The NITRO fits perfect through all my doors. And here is my favorite part. I was exhausted when it arrived yet too excited not to put it together and try it. Well, it comes out of the box fully assembled! I was thrilled. One more thing. This is not a piece of junk. It is super sturdy and quiet as a mouse. Enjoy!
