I bought this for my husband for his birthday and he LOVES it!  We've only had it for a few days but he's used it everyday so far and, sometimes, multiple times in one day. 
While we did take it out of the boxes together, he was able to put it together by himself without an issue.  He probably could've removed it from the box alone too but we didn't want to risk damaging it or cutting it with a box cutter.
