We’ve got the 6ft Chartwell runs from home and roost and to be honest they are ok... just not brilliant.
The 6ft one has an annoying supporting beam running down the middle of it which is a pain in the bum when you are in and out and having to jump over it to get from one side of the run to the other.
The woods quite thin too and my screws would constantly always come loose no matter how much I tightened them but maybe I just got a bad couple of runs.
We would recommend Manor pet housing, they built our bunnies new enclosure and will build anything to any spec you need but are quite pricey. Totally amazing quality though and will last for many years
