Assembly went reasonably smooth. The instructions are decent, but do contain typos like "it" instead of "if." One detail not specified in the instructions is that the upright bars which support the motor mount must have the pretapped holes facing out. Later in the build I realized this AFTER lifting the heavy motor assembly in place. I double checked the directions and they do not specify any detail about this. In the final assembly I found that the "hand" threaded bolts could not be turned by hand because they spray paint the metal AFTER tapping the holes making them too tight to hand-turn. I used vise-grips to tighten them. It would be nice of they had a hex head or allen key insert on the inside of the "hand-thread" bolts so scratching up the hand-tread with vise-grips would not be necessary. Another issue in final assembly was that the holes for the motor mounts didn't quite line up. Had to use a rubber mallet to position the motor assembly down tighter onto the upright bars. This is pretty typical of Delta quality. (I have a Delta jigsaw, table saw, and drill press -- all three of which had initial assembly quality issues).

Overall assembly was a 2.5/5 given the problems. It took about 45 minutes (a bit more than the 30m the manual suggests) because of the above issues. In terms of assembly and parts quality, I think you'd find better quality with Powermatic or Grizzly. For the money, the Grizzly hardware is, imho, the best you can get. But if you are looking for lowest cost Delta is often just that. With sales their prices are something incredibly low. In this particular case you can find the Grizzly 1 1/2 hp or Grizzly/Polar 2 hp dust collectors right here on Amazon (prices are comparable but I don't think Prime is available for any of the Grizzly gear).  I personally recommend the Grizzly (i.e. G1028Z2 or G1029Z2P)

In terms of use, setup of the bags and ducting went smoothly. It has two 4" duct intakes built into a Y. It includes (thankfully) one cover. I would have preferred one 3" intake and one 4" intake for my different hardware, but reducers are readily had and with 2x 4" intake you can run intakes in both directions in your shop.

It is certainly more quiet and cost effective than a shop vacuum cleaner. It is louder than some Grizzly machines that I've heard, and definitely louder than one Powermatic that I've used. But it is so much less loud than any of the woodworking machinery that it doesn't matter in terms of overall volume.

One thing I really think is missing is a current sensor and plugs. Many machines like this (include many shop vacuum cleaners) have a plug/outlet combination that senses current from a tool plugged in so that the dust collector goes on automatically when the tool goes on. Unless your use is very occasional I think this is a must have. You can put this together with parts, but it is a shame Delta doesn't include it. Finally I have three other gripes. One -- the power cord is way to short. I barely reaches the floor behind the machine. Another 2-3 feet would be preferred. Two, the switch is WAY in the back of the unit. This is, imho, the worst design flaw of the machine. I have to rollout out the machine to turn it on/off. Especially if there is an emergency (a bag blows out), you would think that for safety, it would be good to have the switch readily accessible in the front. Finally, there are no stops or brakes on the casters. This is SUPER ANNOYING as it too easily moves. How hard is it to include casters with brakes ?

One final word which is not a criticism, check your ceiling height. In my case this fits between the floor joist up in the ceiling of my shop, but this is quite TALL. If you cannot fit a "stacked" dust collector like this you might consider the 1HP Grizzly which is definitely shorter (G0583Z ).
