I initially started with one Spintec discharger and thought it was OK; except for the poor display and that it only worked on 6 cell packs.
The display on the Trinity unit is vastly improved and they have a switch to go between 4 and 6 cell packs. I now have two Trinitys and have sold the Spintec.
Other difference is that the Spintec discharges at 35A while the Trinity is at 30A. Not an issue for me.
Yes, they work fine and cost a lot less.
