I bought a small Petcube from TSC and it worked fine for about a month before it stopped working. By then I was past the 30-day return window, so I contacted the company directly. They gave me a few things to try, but nothing fixed it. They were even about to send a replacement until they found out I live in Canada, then told me they don’t service anyone outside the U.S. Why sell them in other countries if you won’t support them? I would never buy any of their products again.
