Just in time - because we should have had a spare! May 5, 2015
Reviewer: Henry Bass from Christiansburg, VA United States  
We used these wheels on our FTC robot in the 2014-2015 Cascade Effect challenge. They were great the whole season, but the weekend before the World Championship, one spike broke.  We ordered online, and AndyMark met us at the tournament with spare wheels! Great customer service, and a great wheel. Thank you!

I wish these were sturdier April 6, 2015
Reviewer: Michael Anderson from Herndon, VA United States  
These mecanum wheels are made from plastic.  So, they are easily broken.  They fit the AM hubs without a problem and once they're on, they work fine.  It's just that the rollers are really hanging out there and they're easy to snap off.  Fortunately, AM has replacement parts (except for the hubs)  But, I'd really like to see some 4" aluminium wheels that fit the AM hubs.
