I have had my Motocaddy M1 which is essentially the M3 with a few less features for about two years. I haven't had any trouble with it in that time. I have the 36 hole lithium battery model. I can't comment on the QOD but you won't go wrong with the Motocaddy.
It folds down quickly and easily. Takes up much less trunk space than similar electric trolleys. It has an easy to read screen telling you the time, distance travelled, battery life remaining etc.
Would highly recommend.
Another one for you.....not nearly as many of those in the States use electric trolleys as over there in UK. I have used electric for nearly four seasons. But I just got a new Clicgear 3.5 push - and now wish I had never played around with electric - Not Needed with the ease of push and lightness of a Clicgear.
Anybody in the Phoenix Metro area as a Wrxer has 1st dibs on my still very good shape electric - the Clubrunner by Motorcaddie.
It is a local Wxers for $100 - paid new w/battery & charger $480 in 2012.
Bump...any reviews on qod?
Can get one for a pretty significant discount but don't want to take the plunge without some input from others.
