We have been using it since last seven good years & it is deliberately giving good results; speed, pickup, weighing capacity, looks & consistent results are consciously visible points.
Only thing is you have to give it good maintenance, & some small careful points needs to be look after, which often kids, girls or ladies are unable to do; so overall people complaint.
Contrary to the belief that it is economical over petrol, it isn't that much profitable. It is only when u use the whole battery life & change it with a new one, your calculation will become somewhat profitable.
Service part also depends only in the town where you reside; if you have good repairers in your network then it will work out otherwise, its a long waiting call.
