I have had dualpro,minnkota,noco and ionic,they have all been good.My dual pro i took out the other day i have owned since 2010-2011 and its been a good one.The only problem i have had with it is the plastic case has some cracks,i siliconed them up and it was still working when i took it out last weekend.The reason i replaced it was because it want charge my lithiums correctly,to use it i would have to send it in 6o dualpro and have it converted to charge lithiums.Buddy that sells electronics sold me my ionic lithium charger,hope it will be as good as my dualpro.If i was gonna be buying a charger i would buy one that would do wet cell,agm and lithiums,noco and minnkota precision will charge all i believe.
