I suppose a wee boast here (or should that be Glee boast).
I have the Tutoro dual feed on mine. I bought it because it was cheap and if I got along with it I'd keep it. Up until then I'd apply spray or oil when I remembered to and usually over applied so I got another job to do just after 10 minutes riding the bike, clean the crap off the rear of the bike and worst of all the wheel. Chains don't need lots of lubrification, just enough. If you get fling then it's too much IMHO and it doesn't have to be constantly applied. I had to find the right drip rate of course but I simply turn it on for a 15 or 20 minutes spell every few hundred kilometres. If I get a few dots of oil on the wheel then I know it's working. I've found this gives me a chain that looks almost dry on the outside plates but oily damp at the pins, rollers and touching surfaces of the inner and outer plates.
Another observation is it has a very small reservoir but it doesn't need to be any bigger if you don't use loads of oil. It will do 1000 kilometres before re-filling with chainsaw oil, yes sticky and cheap too. The reservoir size also alows it to be easily located, I made a short bracket to mount it vertically as the bike's frame isn't easy to fix to otherwise:
It is simple to refill/clean/service there too.
to the testers, they got it spot on!
