I'm looking at the Flow-Rite Pro-Fill battery watering system for my Allegro. From what I have seen they seem to work well. Does anyone have thoughts on these?
"jwmll"....If it works for you to move the slide in and out, slide out the tray and unscrew 12-18 caps and carefully fill each one, more power to you. The other 17 posters found it easier to use the ProFill.....you know, that gimmicky gadget!
