TL;DR: Overall value - This sprayer is very easy to use, durable, very easy to clean and produces great results! For the price, it is a great value for the money. Below is a more comprehensive review if you are interested.
Delivery - ordered on a Friday, expected delivery the following Thursday (~6 days). Pleasantly surprised that it arrived Monday (~3 days) with free shipping.
Packaging - parts are pretty durable, so the basic packaging was adequate and all parts and documentation were contained in the box as expected. Not worthy of an "unboxing" video, but totally adequate.
Instructions - basic, but easy to understand the assembly, use, and cleaning of the paint sprayer.
Build quality - There are not a lot of moving parts. The compressor housing has a nice durable plastic casing to protect it and the handle has a comfortable grip. The nozzle assembly is made mostly of thick plastic components that appear to be quite durable and the nozzle itself is high quality brass.
Accessories - the kit includes a number of different sized high quality brass nozzles to choose from depending on the viscosity of the medium you are painting with. The kit also includes a cleaning brush and a nozzle cleaning pin. Included is a small funnel to help identify the viscosity of the paint. Also includes a lid for the paint reservoir in the event there is leftover paint.
Setup - Setup is simple. The main three elements are paint viscosity, nozzle size and flow. Your paint will come with instructions to tell you the ratios and material to use for thinning it and it may even recommend a nozzle size for sprayers (the primer I tested with had to be thinned with water and it specified a recommended nozzle size). After getting the paint to the right viscosity and choosing a nozzle, dialing in the paint flow is a simple matter of turning the dial behind the trigger which controls the amount of opening/flow from the paint reservoir. It took me a couple of tries to get things fully dialed into my liking, but after that it was simply getting paint onto the thing I was painting. Test this on a sample or start out far and get closer to identify how far from the object/thing you need to be for a nice thin coat.
You can also orient the output into a vertical or horizontal oval pattern, or a more uniform circle. The instructions also indicate you can orient the paint intake tube forward, backward, or any particular direction based on how you will be holding the sprayer to get the most out of the paint reservoir (you want the tube forward if you will be mostly spraying downward, facing backward if you are mostly spraying upward, etc.).
Operation - Once you get the paint flow dialed in, operation is as simple as pointing to what you want to paint and pulling the trigger. Keeping the sprayer at a right angle to whatever is getting painted helps maintain an even coat. Keeping the sprayer in motion also helps to ensure the paint doesn't build up in one spot.
NOTE: make sure you are wearing proper protective gear (mask/ventilator, ear protection, safety glasses) and make sure you are in a ventilated area when painting.
Results - Finish results are excellent as long as you have the viscosity, flow and nozzle dialed in. Putting on multiple thin coats is preferred and it produces a surprisingly smooth finish. If you are painting for a long period, be sure to check for build-up on the nozzle and clear it periodically to keep the flow coming out smoothly. I didn't do this at first and it started to produce a bit of light spatter when starting a paint flow. Clearing the buildup on the nozzle with a paper towel resolved that immediately.
