I have 2 Raptor wheels, a fast track wheel and 2 Custom Cruiser wheels. I have 3 cages 1 has an old Raptor, one has a fast track and one has a custom cruiser in them. I use my 2nd custom cruiser in the bathroom for out of cage play.
My preference is the custom cruiser for a few reasons.
1 it's the quietest wheel out of the 3 kinds I have.
2 It's the best quality materials and heavier than the other two
3 you get the wheels fast there is little wait time
4 She stands behind her wheels and their quality.
5 customer service is impeccable, Bourbon Hackworth makes them.
The Raptor wheel is my 2nd fav. However, it can take more than a month to get one sometimes 4 months depending on how backed up the orders are. David Watkins makes them and is very reputable however, not so great at corresponding with customers.
Fast track's are ok and offer different colors than Raptor and Cruisers, however they aren't as of good quality and I've heard ( but not experienced myself ) that their customer service is serious lacking.
My one dislike of the Cruiser is it automatically comes with a floor mount and I prefer wall mounts, however you can request a wall mount. The floor mount will need to be secured to the bottom and wall of the cage with either fleece or zipties.
Having said all that, the reason they automatically come with a floor mount is actually a safety feature of Custom Cruiser. The floor mount ensures the wheel is at least 6 inches off the floor of the cage. Any lower to the floor increases the risk of injuries. So, please keep that in mind no matter what wheel you go with, make sure it's at least 6 inches off the floor even if you go with a wall mount
All 3 of my wheels in use are pretty quiet, but the cruiser I have to literally put a noisy hanging toy above it just barely touching the wheel to even hear that they are using it.
Personally I think the gliders themselves are louder than any of these wheels, especially if they have a bark fest...
If you go with a Cruiser please tell her Carla Sloan sent you
