FLEXiO 4300 is rated 4.0 out of 5 by 12.
Rated 1 out of 5 by from Not helpful costumer service. The guy sounded like no comparison on the costumer at all. I am a first time user and having trouble with my new Flexio 4300 having air leaking out from the valve and spitting out big particles of paint. I did take it apart and clean, tightened, same thing. To make it short, I was just told return the item back to where I got it from. OKAY!

Rated 5 out of 5 by from Great device . Works like a charm ! I just purchased a flexio 4300 . I have to say that the start was a little rough but once i figured out the right pressure to set the gun on. The rest after that was history . Flexio performed like a champ . I would definitely recommend this product to anyone wanting to paint easier than the traditional way

Rated 5 out of 5 by from Easy to use I am so impressed with the sprayer, easy to use and easy to clean which is important after you have sprayed for several hours. It accommodates my small hands being a woman!!

Rated 3 out of 5 by from Over all yes, but cup is hard to handle and leaks I have overall been pleased with the way this product operated for my project. It proved quick for my project verse a brush or roller. It put the product down evenly and quickly. It did however leak from the cup as it was difficult to tighten.

Rated 5 out of 5 by from Very easy to use! This product is so much better to use and clean up after completing my project. I began my painting project using another style of spray painter. The cleanup was terrible, but was much easier using the FLEXiO 4300.

Rated 4 out of 5 by from Very impressed! The Wagner Flexio 4300 is awesome! This is truly one of the best DIY sprayers ever. With 3 different sizes of spray cups it can handle large rooms wall to celling, decks, sheds, fences, furniture, cabinets, trim, small arts and crafts you name it, it can spray it. With a tough and flexible16 foot air hose there are few things this can't handle. Clean up really is 5 minutes. Wagner has done a great job making everything easy to assemble/disassemble. All the parts fit together nicely and the finish is nice. One of the only real draw backs I've found is with the gravity feed cups. They are tall, so tight spaces like book shelves or inside cabinets might be difficult to access. Overall this is such a fun, versatile and easy to use sprayer that is perfect for around the house. Disclaimer, I received the Wagner Flexio 4300 free of charge for an honest review. With that said, this is my favorite sprayer and my new go to. I love this thing.

Rated 4 out of 5 by from Good home project paint sprayer This was sent to me to try out and review. Was able to use it twice since receiving. First off, it was easy to use and easy to clean after using. For my first project I sprayed a backing for a hook and ring game. The sprayer gave it a nice even first and second coat making. Clean up after was a breeze and I couldn’t wait for my second project! A week later I used it on a ping pong table I made. Had a few issues with it spitting the paint out but after thinning the paint it worked fine. I recommend making sure it’s spraying the way you want it on something that is not what you are working on before jumping right onto your project. This is a time saver for sure compared to a brush and roller! It comes with a bag to keep everything but the actual machine/turbine in. Everything from setup to cleanup is easy enough that i think anyone could benefit and save time using the Flexio 4300! Can’t wait to use it to stain my deck next!

Rated 5 out of 5 by from My favorite so far I love Wagner products. In fact, this is my 4th. It's very well built and very efficient. As with any sprayer, you have to take a minute to get your spray pattern and flow speed set, but I don't believe you'll find a sprayer that's easier to set up. Clean up is a breeze. And it has a storage bag that hold everything except the pump. Or it could be that I'm not organized enough to figure it out. This little unit will make you want to start the next painting project.

What are the differences between the 4000 and 4300?

Asked by: Tony141
The only difference is the gravity cup setup for the 4300. Otherwise, they are the same system.

I’m painting kitchen cabinet doors, and looking for a very smooth finish with semi-gloss urethane alkyd enamel.  Is there a difference between the gravity-feed nozzle and the detail nozzle?  Which one is better for smooth cabinet doors.

Asked by: Peterchr
Both setups would provide the same results and finish. They are the same nozzle, just the cup location is different. For more information call us at 1-800-328-8251.

The 4300 case is too small to fit well all the components, how do you fit and organize all the components in that small bag? I like the neat organized hard case of the Flexio 5000 I was debating to go for that

Asked by: Bimal
The soft storage bag that comes with the Flexio 4300 is meant for the small items, not the hose or the turbine. Everything else should fit. For more help call us at 1-800-328-8251.

Can I use this to paint house outside?

The Flexio HVLP models are "project" sprayers, but you can paint the house, you'll just have to fill the cup more often. For application tips, call us at 1-800-328-8251.
