I've come across a Casio MQ-1 that's unboxed, but still with the instruction manual. The manual is water stained so the MQ-1 might be damaged. I've tried 1.55V Alkaline batteries, but don't have the 1.5V silver oxide batteries that the manual specifies, so it may work, it may not, but I didn't know if costumers cared if it works or not because I read that they usually take it apart anyway?
Any thoughts on what I should put it on Ebay for, if it's not a working unit but is undamaged on the outside?
Thanks for any input,
