Yes... I do have an update on this post for all interested parties. I will give the gold medal to "The Carboy Cleaner"!
Why? Because its rigid (stainless steel rod not plastic), its got replaceable pads in 2 different sizes, and its pads are also more rigid which helps it to extend to the walls of the carboy. Granted, it is more expensive, but it works better and is more durable than the Clean Bottle Express.
If you hate using that carboy brush you should buy the Carboy Cleaner. It hooks up easily to the cordless drill and all you need is about a gallon or two of water with some oxiclean in the bottom of the carboy and its done in seconds!! Awesome...
