    • Fast arrival, and great German 24 volt performance!
Style: Paddle Switch - Tool Only
Just received this 2 days ago, and what a great portable grinder! Used yesterday for the first time to sharpen Mower Deck Blades, and love the light weight and no power cord. Unit was easy to handle one handed (without using the side handle), and has plenty of power. Also loved the variable speed feature and simple switch. Unit arrived within 2 days and exactly described by seller. I've had great experience from FLEX tools for the past 4 years, and just had them replace a battery under full warranty! Always register your FLEX products for lifetime warranty. I highly recommend from a former Bosch customer. ... show more

    • Superior Tool For An Affordable Price
Style: Paddle Switch - Tool Only
Excellent Angle Grinder I like the paddle switch and the quick adjustable guard. I've got just about every tool Flex makes that I need. They're a bit heavier than some of the other tools, but they're so much more superior.

    • Great product !
Style: Paddle Switch - Tool Only
I have most of the Flex 24v tools. This grinder was very high quality & loved the ease of operation such as changing the grinding wheels & loved how the trigger works.

    • Better than all the other cordless angle grinders – except for one weird design flaw
Style: Paddle Switch - Tool Only
Better than all the other cordless angle grinders – except for one weird design flaw I have used many different cordless angle grinders and this FLEX 5-Inch 10,000 RPM Variable Speed Paddle Switch Angle Grinder is the absolute best one I have ever used. It has many great features: plenty of power, variable speed, tool free easily adjustable blade guard, cleanable air filters for cooling air, exhaust air blast forward, and LIFETIME WARRANTY if you register it online. This tool is UL Listed meaning it has passed stringent electrical safety testing standards; same with the rechargeable lithium batteries and battery charger. I have major name brand tools that do not have this electrical safety testing certification. My only complaint is the strange forward angle of the side handle. The pictures don’t’ show this design flaw in proper perspective. The side handle (either side) is installed at a forward angle placing your hand closer to the surface you are working on. Every other angle grinder I have used has the side handle mounted perpendicular straight out from the tool. I am going to have to get used to this strange awkward forward angled side handle. So far this weird side handle angle is still awkward to me. So, I took off one Star Rating point. If I decide that this weird side handle angle is acceptable, or even has some advantage, I will change my review. ... show more
