Review: QUALITY & BEST VALUE - 🔴🚨 ✞ 🇺🇸 THANK YOU FOR YOUR GREAT QUALITY WORK..💥 🔴🚨 ✞ 🇺🇸 THANK YOU FOR YOUR GREAT PRODUCT & VALUE..💥
Review: Helps expensive brushes get cleaner and last longer, and has stayed rust-free so far - This works great for my purposes. Primarily I use it for two jobs... Firstly, I use it to pry open paint cans using the tip on the hooked end (which works better than a screwdriver in my experience, because screwdrivers tend to bend the paint can lip). It's odd the manufacturer doesn't mention this function on the product's label. Second, I use the brush cleaner comb during brush washing, which makes the whole cleaning process go faster. It really helps you get into the nooks and crannies of the brush. I have also used the tool to help clean paint from a 9-inch roller -- which requires some vigorous scraping of the tool along the roller -- but honestly I was disappointed how much work it is to clean a roller. After 5 minutes of running water and scraping the roller, and rinsing and scraping some more, my roller still wasn't totally clean. So I went back to tossing my rollers in the trash when the painting job is done. That's not the tool's fault -- it's simply an unavoidable amount of hassle and huge amount of water to clean a roller. So far the tool hasn't rusted despite being used for perhaps a half dozen painting jobs and brush cleanups. I have never tried the nail-related feature, since I'm afraid I might break the tool, and I have a claw hammer for that anyway lol. My only (tiny) complaint is that this tool doesn't also clean smaller 4" or 6.5" rollers (wrong curvature), but this tool wasn't designed for that anyway, and you can find other roller cleaners that do that elsewhere on desertcart. Those little rollers are so cheap -- just a couple of dollars each in a multi-pack -- that it's not really worth the effort to clean them anyway, IMHO, so this isn't a big complaint. Overall this is a very useful tool to have around when you're painting, and it's not expensive, so 5 stars from me.

### ⭐⭐⭐⭐⭐ Great taping knife and customer service
*by A***O on July 8, 2020*

This is an excellent product as it is thin and much easier to use than the cheap disposable plastic ones. It is pretty flexible and it can press well on the wall to spread the joint compound pretty evenly and flat. The handle is sturdy as well. My first one arrived damaged as the rear cap felt off during shipping. The replacement came quickly and I am extremely happy about it. Since this taping knife has higher carbon content. it cuts the compound very well. However, it will rust if you don't keep it dry after wash.
