Hi all Silent Partner users. I got my machine right at 3 years ago. It has EDGE written on it, but I think that is the series and the model I have is the Lite. Any way, it's been great for the first couple of years, but it has been going through batteries pretty fast. They just don't seem to hold a charge after a while. I was using cheaper batteries from Batteries Plus, but I did go ahead and break down and order one from SP directly. It's just not any better and about a few weeks ago, it starting having issues feeding the balls. Before I call SP and committ to anything, I was hoping for some feedback about how long I should expect these things to last, is it repairable, is it worth the cost or repair etc. Any feedback is greatly appreciated. Thanks.
