I think you'll enjoy the Volt. The wife still loves hers but I'm in charge of keeping them clean (sigh).
Note that they will gunk up on you and stop charging/performing well if you don't keep them clean...so do. I use a toothpick to dredge out the gunk around the center post and then place them threads-down in a small container with just enough pure grain alcohol (everclear, etc.) to cover the threads and let them soak for about 5 minutes or so. Take them out and shake them like a thermometer to sling the alcohol out, away from the batt. Repeat if necessary, wipe out with a paper towel and done.
