problem with purple and orange motors??

[skklown]

i recently e-mailed radioshack through zipzaps.com and told them how my purple and orange motors were slowing down to the point that my friends red motor would straight out beat them. just today i recieved an e-mail from them. they said it was not normal and that zz motors have 90-day warranty on them and to take it back with the e-mail and reciept to get a new tuner kit. later today after my guitar lessons i will be stopping b and exchange the kit. hopefully the motors wont burn out as fast or at all!!
