Summary: Great addition to my workship!
Comment: I don't think I can say it much better than most of the other reviewers here, but that's never stopped me before.
It's a very well made product, from the mortiser itself, the very sharp chisels that come with it and the chuck key. However, the hold down does leave a bit to be desired. It doesn't give me that sense of confidence at all times as far as whether or not it'll stay put...but it has so far.
Personally, other than the hold down, I love this tool! If you're drilling holes and chiseling the waste wood or routing...well if you've got the dough (and in this economy, it's an understandable consideration!), give the Jet a looksee!

Summary: As expected-- makes square holes
Comment: Finally decided to try a benchtop mortiser and with the rebate the Jet looked a bit better (i.e. cheaper) than the other options. Contrary to some of the recent reviews below, mine arrived without a scratch in a pristine-looking box-- and just three days after I ordered with free shipping. Can't argue about that. This is my fifth or sixth major tool purchase from Amazon (inc. jointer and planer) and I've always had excellent experiences with their shipping service.
Assembly took less than ten minutes and I was making sawdust soon after. The unit actually comes mostly assembled; all that has to be added is the arm, fence, and table. Nothing was slathered with grease! As others have noted there's a hydraulic cylinder on the head that doesn't really seem to do much, but I found the action to be relatively smooth without it. My test cuts in red oak went in easily and the bit did not clog. My next purchase will have to be the proper stone to sharpen these chisels; the were quite sharp out of the box but I'm sure will dull quickly as well.
At this price point, with free shipping, I think either the Jet or Delta would be acceptable. It's not exciting but it makes square holes. If you do a lot of M&T joinery or are making Craftsman furniture as I am (doing a bed this summer) it should be a real time saver. Otherwise, you may want to save the space and just use your router and a hand chisel to square off the ends.

Summary: Jet Bench Mortiser had some quality issues
Comment: When I received the mortiser, there were no obvious signs of damage. However, when I opened the box I found the top fan cover was dented in so as to impede the movement of the cooling fan. It was easy to pound back out and there is no paint or structural damage but it should never have left the factory that way. Also,the post that the hold down clamp secures to has a set screw to hold it tight and that was loose from the factory. There is no wrench included to tighten it and it took a while to find one in my collection that was close enough tighten it. Just a pain in the neck. Once I got going, it performed as I would have expected although I will probably get a better set of bits than the ones included.

Summary: Good machine, bad QC
Comment: I used my neighbors machine... he has this same machine, I was so impressed, I ordered it the next day.
Mine arrived very quickly, amazon is great -- the packing was perfect, but the machine looked like it was assembled by monkeys!
The fan and fan cover were beat up and broken and one of the screws was cross-threaded. Yeah, they are sending me new pieces, but what a bad QC job!!
Customer Rating:
Summary: short mortiser
Comment: This is not typical Jet equipment, I have a Jet table saw, lathe and band saw, they are impressive tools. I should have read the small print with the mortiser. the throat is just enough to mortise a 2X4, in hard wood the motor jams because of wood chips, the chuck is too small 5/8ths would have been a better choice and hard to access. I did keep the machine and added a spacer for wider stock. It does work better than my drill press but not much.
