Review on 🚀 FIRSTINFO Aluminum Pneumatic Aerosol Refillable Pressure Storage Sprayer Can with Dual Purpose Nozzle for Jet Straight Stream & Mist Spraying Kit - Compressed Manual Fluid Oil + Jet Dual Purpose Nozzle by Jerry Estrada

First of all I would like to say that I am pleased with the overall quality of the product. I sometimes have trouble aligning and filling it properly, but I think it is related to the inflator ie my tire pump and NOT the device itself. I use it in my car service and am very satisfied. I use it for WD-40 applications. Mainly for lubricating aluminum parts when machining on a lathe. I used to buy an aerosol can of WD-40. No more empty cans! Also, the aerosol cans sometimes lost so much pressure that although I could shake the can and see that there was still a significant amount of product inside, nothing came out. Complete loss of pressure. I love the fact that I can always add print to my refillable pad. Other than that, I haven't lost any pressure (ie it hasn't leaked) with this product yet. If you fill the device with more liquid than you have, you can fill the rest with compressed air. or vice versa, it is possible to have very little liquid and more compressed air volume. I can see that some people have issues with him not putting enough pressure on them that they want. Just try filling with less liquid and more compressed air. That can help. As for me, I am completely satisfied with the device and recommend it to anyone who understands how it works. I don't recommend it for use as an air dryer (just blows out air, doesn't fill liquid) although I found it worked great in that situation, just remember it's compressed air, not CO2 based or anything .
