I am just about to sign up for 5 units
Maybe I will wait..........
I would not write them off, but I would wait to see if they sort this issue out.
When the units work ok they are good and I find it very useful, I have not noticed much of an improvement in fuel usage but to be fair to my lads i dont think any of them took advantage anyway.
The biggest advantage is from a logistic point of view.
Apart from the downtime issue my only real issue is with how often the data is sent back.
If your running a haulage company the pre set package of sending a signal at every "event" or every 1000 yds is great, but for us its not enough. if you have a van moving at slow speeds in built up areas you miss a lot of the route.
This can be altered though, They only allow a certain amount of uploads per month from the unit, a long distance truck will send thousands but I cant see us getting anywhere near, so my advice is to give it a couple of months then talk to them about adjusting it to suit your needs.
