my dodds been flawless except when I accidentally left it on too long got the beeps, recharged and good to go
FYI, if you leave it on too long after the beeping starts, it will damage the batteries to the point that they cannot be fully recharged. I have - twice - accidently left mine on overnight. They will recharge, but each succssive use will result in a shorter live until you have to replace the batteries after 4-5 listening sessions. I am much more careful now :)
Also, as an FYI, I have found a battery sold by the franchise store, BatteriesPlus. It's their Werker brand. It's pricey (they will discount if you buy four), but it works very well and it fits into the pre much better than the Powersonic brand Gary last sent to me. Plus they are sold with a one year warranty.
