I like the topspin 12s, don't have problems with them not being even infact thats the whole point of having it set up like that! Their main selling point is the equal pressure and I think it is alot better than standard dripper fitting which cheap nasty and break easy with crazy uneven pressure.
Topspins need enough pressure to create equal pressure though. If you get a pump which is not powerful enough then yeah it won't work great. Simple to avoid really. I just upgraded to the high pressure 25mm version and it works an absolute treat.
Topspins also have an additional central filter and then filters on the connectors for each line. Stops the actual drippers clogging so you just open the central hub and clean that instead of each dripper.

herb ive used topspins for the past 3 yrs and had no problems at all . each dripper gives out bang on 500ml per 15 mins ( b4 i started my 9 kq grow i put each drip line in a milk bottle and ran it for 15 mins then checked in a jug its was bang on 500ml . ive neva had blockage in a drip line as well ... im useing the mj1000 pump , nun rtn valve and filter as well ....
after this 9 are finished i am cutting numbers down to 4 so i will be useing bigger pots and growing bushes with 3 drip lines per pot ...
