After trying three other walkers, THIS ONE is THE BEST! The wheels climb carpet edges easily. The walker is an inch narrower than most of the rest, which means it fits through my bathroom door without banging up the woodwork. It's easy to push. My feet almost never kick the walker. It's comfortable to sit on -- why aren't all the back rests curved? It's light weight (about 13 pounds without the basket). It folds easily. There are lots of great accessories available for it.
With two wheels that swivel and two that don't, it can turn almost in place without me having to lift anything. This is a great blessing for tight spaces and dead ends.
THE BRAKES WORK VERY WELL -- the BEST brakes of ALL the walkers I've tried. They grip the wheels firmly without slippage (not true of other brands). The squeeze handles need only modest pressure, and don't require a long squeeze. The brakes don't go out of adjustment easily (other brands do). Nova has such faith in their brakes, they give them a 5-year warranty.
I like this rollator so much, I've bought two of them -- one for in-the-house and one for outside. This means I don't have to carry it down the steps to get it outdoors, and it also means I don't track outside dirt into my house. (Yes, I'm one of those people who takes his shoes off when entering the house.)
The "indoor" walker is equipped with the plastic tray and the flashlight. The tray makes it easy to transport things that roll (the tray has a lip around it); the tray comes off easily (just lift) when I want to sit. The flashlight is wonderful for late night bathroom trips without waking up my wife. Yes, the flashlight uses LED bulbs, and casts a broad, bright light that you can aim easily.
I *LOVE* my Nova Rollators!
