I forgot I had these, but here are 3 safety recalls.
First ones are for a fire hazard on the X300, X300R and X304 sold between September 2010 and July 2011.
The second one is for brake failures on the D100 sold between October 2010 and September 2011.
The last one is for a laceration hazard for the D series sold between December 2010 and September 2011.
I would expect any owners would have gotten their notice already, but just in case they didn't or if these units are now being sold used, it's something to check.
