Gel Blaster Surge 2-Blast Mode Water Bead Blaster, Extended 100+ Foot Range + 10k Gellets

We bought two Gel Blaster Surge blasters for Christmas. They are the exact same model. One works perfectly, but the other does not work at all. We charged both for over six hours as instructed. The working one is fine, but the other says it's fully charged and then immediately has no charge. After reading other low reviews, it seems many people are having the same issue. This was a big letdown, especially for a Christmas gift. Quality control is clearly inconsistent.

Neither one would charge after about two to three very shallow battery cycles. im pretty sure these were new old stock, as the packaging was pretty faded, and a bit worn. I kind of suspected that was the case going into it, but it was about 1/3 of the price that they are normally so i took a chance. If anyone else has this problem with these, and you are handy with a soldering iron, its pretty easy to fix. its not the batteries that fail, its the charging circuit itself, so it can be fixed by straight wiring the battery pack to the switch, and motor, bypassing all of the circuitry inside. this is how the pirahna is designed, same wire guage, same switch, same internals, just a different casing on the outside. well im done pooping so ttyl lol!
