Shift.ms is better if you're logged in

I mobilise with a crutch, sometimes 2 due to balance issues. However recently I have been looking into and considering a rollator (walking frame with a seat) to allow me to walk for longer periods as I'd really like to try to exercise a bit more, but I haven't taken the plung yet as I go from thinking its a good idea to get me moving more to thinking its a ridiculous idea and I shouldn't be using one. What are peoples thoughts? Has anyone else tried something like this to get them moving more?
