I have had my rebuilt rainbow for 6 months and it works like it was new, I had a little problem with the power hose and I just emailed to ask a question and they just mailed me a new one with no questions asked. You don't get that kind of service any more I would highly recommend Great Vacs to any one.
The product is exactly what I was looking for. I dislike the fine scratches on the edges.
After using my Kirby vacuum for a while now I can say that it works better than expected. Solidly built and easy to use.
