TLDR: Great for small to medium projects, unbeatable flexibility, but a bit on the heavy side and is a battery hog. More batteries/charger required for normal use. 4/5 overall.

Bought on eBay new in box for about $170 USD, came with a charger and two Wagner-branded 2ah batteries and a charger, also a normal paint nozzle and a "detail" nozzle that I haven't used.

Ease of use/setup 5/5: very easy and intuitive if you've used this style of painter before. Fill with paint, attach and lock the motor housing to the nozzle assembly, and go. Simple on/off switch, in the on position the fan motor runs at a low speed, and when pulling the trigger the fan speeds up and also opens the paint nozzle.

Flexibility 5/5: various settings on the painter to control your work for different paint types or stain. The trigger has settings 1-12 (it's a dial that limits the distance the trigger can be pulled, affecting the paint nozzle opening size), the nozzle can be rotated horizontally or vertically, and the spray width is adjustable with a dial. The motor has fan speeds 1-5. The instructions give detailed recommendations for types of paint/station for each setting.

Coverage and spray quality: 4/5. I picked a terrible day to paint. Windy, hot, and dry. The paint was dry to the touch almost as soon as it hit the doors. While tack-free time was great, the surface finish could definitely be better, the paint didn't have time to even out. That's not the sprayer's fault. However, the atomizing of the paint could be better and requires constant attention. My paint was pretty standard latex, and while 90% of the paint was atomized, I had to keep and eye out for larger specks and wipe them. With more use, the nozzle gets paint around it, blocking airflow. You need a wet rag with you at all times to wipe the nozzle clean every 1-2 minutes. The coverage and speed are decent, you wouldn't want to paint your whole house with it, but great for small to medium projects.

Battery life: 2/5. Chews through batteries. With the provided 2x 2Ah kit, you could not paint consistently, I was able to paint full-time because I have the 6-bay charger with an array of batteries, but you get ~6 minutes (estimated) of use per Ah of battery on the highest fan speed. I had the most success with 8ah batteries. After a battery dies, it may be too hot to charge anyway (YMMV, I was painting in 95°F/~35°C)

Ergonomics/Weight: 3/5. Comfortable enough to hold, the grip is rubberized and it's well balanced, but with a full pot of paint and a 4/8ah battery, your arm will be tired and I found myself switching arms back and forth. It's not as bad as a framing nailer, but you'll feel it. It's not quiet, but not loud either, nor is the tone of the noise very annoying. With a 2 or 4ah battery, it sits nicely on the battery guard and paint pot.

Cleaning: 5/5. Comes apart extremely easily, all parts are clean up quickly and there's nothing small to lose. They provide a brush in the box. The entire motor assembly disconnects from the nozzle, preventing damage to the fan/electronics when washing.

Value: 2.5/5 @ full price ($319-349 USD), 5/5 @ third party pricing (eBay, $175-200). You basically have to be in the Bosch/AmpShare ecosystem for this to make sense, as the included batteries and charger can't keep up with the use. I would be disappointed if I had paid full price, so if you're interested, keep an eye out for a deal.

Of course this isn't all-inclusive, nor does it pertain to any specific region, only new three-character model numbers that have been added to the parts catalog:

GVC18V-25-120D 18V Concrete Vibrator (handheld- not to be confused with new backpack solutions)

GPA18V-35 Cordless Drain Snake
