Very happy with my purchase. Works amazing for our needs, easy to fill up doesn’t leak and the nozzle is perfect for our glue application. I was looking for the 6 âï¸ button, but looks the 5 âï¸ is the best i can do. Thank you.

I'll post some pictures soon. I am currently refinishing cabinets in a luxury home. I say that because I was scared to repaint my high end quality built cabinets but my wife wanted them updated. The only issue I had as a first time sprayer was dialing the unit in. Be patient, take your time and once it is adjusted properly it is just an incredible little sprayer. I am spraying with latex paint and I thinned it based on several youtube videos. Finally it is easy to clean once you realize that it is necessary to clean out all the 'holes'...buy it. Oh running a small 15 gl compressor and it does the job.

I bought the gun after reading every review. I used to spray cars in a body shop and when my primer suction gun of 20 years finally went I researched this one. Honestly after running a gallon of automotive primer thru the gun it took almost as long to get the darn thing dialed in as it is very awkward with adjustments that are hard to find a happy spot. When I first got it I washed it in thinner to clean out a bunch of dust and debris from the box. I had to tighten all the nuts as the packings were all loose. Again, it took a while but it does spray automotive primer pretty good with the proper attention. Right out of the box it needs some love; just so you know. If I had to do it again, I probably would not buy this gun. I would spend a bit more and try a different model. Astro was the model I owned before and their quality was always good so felt safe buying it. Heck, I got 20 years from the last one. I'm sure this one will not go that long as the needles are 1/2 the diameters and it does not feel comfortable while spraying. I am used to spraying with this type of gun and this particular model just feels cheaply designed.

It's perfect for it's intended purpose. This is an Automotive/Urethane/Acrylic lacquer/Enamel type gun.You are going to need to know what you're doing. It does need other equipment and supplies.Although I have read some have been able to spray Latex by watering it down this is notintended for that. That's what "Airless sprayers" are for (Wagner/Graco etc.). I'm using it forAcrylic Lacquer Primer and it is perfect in my shop. Low cost and I don' have to worry aboutit hardening up in the cup. Add a little thinner in the morning clear the cup air hole with a paperclip or wire and off I go. I don't even clean the thing other than the cap when itgets to gummed up. When it finally takes a dump I'll just get another at $30 bucks. Time is money !!!!

This sprayer worked as advertised and better. I used it for spraying stain/sealant on a fence and it worked like a charm with my 6 gallon compressor. You do need to pay attention to the instructions and reading the other reviews is wise because they give some good advice. It takes some time to get used to how to set the sprayer up and use it but once you get the hang of it you will have no problem. I replaced a very expensive sprayer that was the pump included sort with this to go with my compressor and I will not go back to the other kind again. This cleans much much easier and is very easy to use. The lower pressure feature is also much less mess. I am sure a painting pro wants the high pressure system but for home jobs this is the best. At this price you can't miss.

Worked okay at first, but nothing compared to my old Binks. Still, I didn't expect much for the price. Using latex extender and getting a good thinness, I was disappointed that it sputtered intermittently. Constant nozzle wiping with a wet cloth, never letting it sit for more than 5 minutes in a humid room, nozzle covered with that rag, and yet still it would start to sputter. I used a cleaning kit on this twice, thinking maybe I overlooked something. Ran Dawn risky soapy water through it, then just water, and even tried thinning my paint even more. Tried a ton of adjustment combinations to try and just stay consistent. No dice.I ended up returning it and upgrading to the Astro AS7SP, similar to a Binks. It works great.

After rolling and brushing 5+ coats on my nightstand, and with multiple colors of paint had issues with bleed while doing the clear coat - I started researching sprayers. I already have an air compressor, so I bought this one to repaint my headboard to match (and for a list of other projects). The clean up is easy as pie, but I'm having a heck of a time getting a decent sized spray pattern. I haven't researched it again yet (will soon) - it's great for smaller projects, but this one is taking longer and requiring more coats than I expected. Still - the headboard frame turned out AMAZING, super smooth and consistent coverage - but the 2 panels surrounded by the frame wound up kind of textured, I suspect from overspray (sanded down smooth easily, so no biggie). I'm using white chalk paint - so that could be part of my issue, but I'll be much happier once I work out the kinks and get a larger and more consistent spray pattern.

I followed the exact instructions that Jake M put in his review and it worked great for painting 6 prehung doors. It takes a while to get the right settings dialed in but by the last 2 coats I had a really smooth finish. My advice is to always work with at least 1/3 of the can full, any less and you will get some splatter. I filled up to about 3/4 full or slightly more and that lasted half the doors on first coat but by the time i laid on the 4th coat it went a long way. I only have a pancake compressor so i paused between each door for the compressor to catch up. This made it take a little longer than brush and rollering but i like the finish better, as i was worried about marks from brush strokes and roller strokes. I also bought the Wagner Flexio sprayer but didnt even open it. Took it back to home depot and saved myself $70!

I'm a newbie when it comes to using a sprayer and consider myself a pro diyer and I found this sprayer to be good quality a d easy to use. I used this to spray cabinet grade acrylic paint on a cabinet project. I could see how this might be a bit small for a larger wall. I wish there were instructions that came with, but I figured it out pretty easily. I used this about 5 different times and as long as you clean it out after each use and make sure you thin out your paint just a little then you will be fine. I used older paint with this too that thickened up a bit, just thinned it out a bit more and it was fine. My little 2 gallon air compressor did have a hard time keeping up with the sprayer when I was heavily spraying.

A great gun for the money. I just finished spraying out a set of kitchen cabinets with water-based Lacquer and this gun did a flawless job. It's as good as similar guns that I've paid twice the price for. As for those giving it bad reviews because they can shoot plasti dip and walls with it, this gun isn't intended for those applications. The paint must be properly thinned to be effective in this type of gun. It is suited for furniture and cabinet finishes, automotive paints and other paints of similar consistency. Take the time to learn how to properly adjust the airflow, product flow and spray pattern before using it on your final piece. If you need help YouTube has lots of videos.
