Battle of the Rollators—Topro Odysse v Acre Carbon Ultralight

I have a Topro Odysse rollator which is ok if not somewhat heavy.
I’d be interested to hear what other users think about this model? The Good, The Bad and The Ugly reviews welcomed.
I’m thinking about replacing it with the Acre Carbon Ultralight Rollator.
Do any other forum members have one and if so I’d be grateful if they would be kind enough to share their views.

The cheaper ones tend to be made of steel and are heavier. Spend a little more and the aluminium ones are lighter. I’ve got a Z-Tec Falcon lightweight folding Rollator which are around £125-140 new but I picked up mine 2nd hand for £20! Worth keeping an eye out on ebay or facebook local ads.
