LitterMaid LM900 reliability Question
 

I've been thinking about getting one now that I have 2 cats.
However both Kage (4) & Thai-ger (.5) like electronic toys and I'm afraid
that they will think this is one and somehow break it.
I've looked on Ebay and see a lot of broken, parted out and refurbished
units which makes me think they are not so reliable.
Any help is welcome
thanks
