Cat's Meow Cat's Meow Toy Breaks Down internet

The Cat's Meow breaks down after a limited time of use.  It eats up batteries like mad so I bought rechargeable batteries and a recharger which cost about double what the toy cost.  But now even with fully recharged batteries the motor only runs for a little while and then stops.  I returned the (two) toys I got and asked for replacement or a refund.  Perhaps if they replace it it will be with a toy that is better made.  I will be surprised to hear from them at all and if I don't I will seek a refund on my AMEX card.
