General User Impressions

The good

DeVilbiss good quality and buyer provider

Several folks had nothing at all but very good to say about DeVilbiss and their customer provider. Some gave a shout out to their consumer service representative by contacting them by title. The occasional poor apple didn’t discourage a lot of from admiring DeVilbiss’ popularity for top quality, and their consumer provider produced up for it with people that have been upset. You cannot go by dealing with your clients like family members.

Bang for the buck

The benefit of this spray gun won more than several individuals who in contrast it to a lot more pricey types from other producers. Quality, delivered at a affordable cost, is usually a winner. A quality product with fewer features will often defeat an common solution with also a lot of characteristics that don’t constantly work.

Sprays and atomizes

In most of the testimonials we noticed, men and women have been amazed by the 3 fluid tips that arrived with this gun and the way it laid down paint, primer, and distinct coat with no managing or dripping. “Clear as glass,” and “amazing” were some of the comments we identified. It atomizes the spray for a around best finish.

The bad


A quantity of people described getting a plastic cup instead of the steel 1 pictured in the ads. This wasn’t a common complaint by any implies, but it occurred usually adequate to make us wonder what’s likely on at the factory.

On the other hand, we identified a variety of evaluations exactly where the customer explicitly said they gained a metallic cup. Somebody at the factory might be cutting corners now and then when the boss isn’t looking. If so, it is not DeVilbiss’ fault directly, but they need to address it.

I’d also advocate viewing this YouTube video for a visible overview:


The DeVilbiss FinishLine 4 FLG-670 spray gun is a high quality product with sufficient functions to fulfill even a picky consumer. It performs the way it ought to, sprays evenly and clearly without working or dripping, and is simplicity itself to disassemble, clean, and reassemble. It feels cozy in your hand and is really properly-well balanced. The instruction manual is easy and consists of an exploded diagram that in fact helps make feeling.

We desire it had a carrying scenario, but that’s really the only fly in the ointment. Aside from that, this spray gun will almost certainly be the final 1 you’ll need to have to buy for some a long time to come.
