Like several reviewers I read during my research, I had never heard of Flex tools. Many report that this is a new, untried brand and were skeptical on ordering them. The actual truth is quite the opposite. Flex tools began in Germany in 1922 (longer than Milwaukee tools). I have been a DeWalt user for 20 years and wanted to change my tool platform to the newer style slide on batteries. I read a lot of reviews, watched YouTube videos, researched the company and found these tools were in the same high end category as DeWalt, Milwaukee, Makita, Bosch etc. In speed tests, they outperform all brands except the newest Fuel series from Milwaukee, where they are neck & neck. Here are my Pros & Cons: Pros: 1. High quality and rugged build 2. Very smooth running Circular and Reciprocating Saw 3. Low vibrations on all tools 4. Like the color 5. Well balanced selection of tools with one exception 6. 24 volts for extra power 7. Good battery life 8. Available Free lifetime warranty extension on all tools, batteries and chargers if you register them on the Flex site within 30 days. 9. The new Stacked batteries are fully compatible with all tools and offer significant increases in power and battery life. Cons: 1. Due to the build quality and rugged design, they are a bit on the heavy side 2. Wish the selection included an angle grinder 3. The trigger on the impact driver is very sensitive, goes to high speed too quickly Flex is now releasing compact versions of most of their tools which are lighter and reportedly the trigger on the compact impact driver is much better. I used the impact driver to disassemble church pews as part of a renovation project at my church. Several people used my impact driver and compared to the DeWalt drivers and my Avid Power driver, it was much faster and smoother running. I am definitely going to stay with these tools. I have already ordered my Flex angle driver. Maybe later some Stacked battery packs.
