Query: Save your money

Biggest $200+ money-wasting mistake I ever made.I have a Rio Cali that works great. I thought the Karma would too. It had nice features. I bought it to use for break music for band gigs.First time using it, it froze up, and never recovered. It is discontinued, there is no support for it, but I knew this when making the purchase.Just trying to make sure nobody else wastes their money.
