  • Strong and sturdy
Style: Multi-Tool - Tool Only
Works great. Lifetime warranty if you register it. Just keep in mind it uses starlock blades, which Bosch invented. Most other blades don’t work. But it is strong and great quality.

Extremely nice oscillating saw.

  • Great price!
Style: Multi-Tool - Tool Only
At the current price, it’s a great deal. I paid more, and I don’t regret buying it. It has low vibrations on my hand but it oscillates more than the other Ryobi and Skil version I have. Super powerful. It can even cut through metal. It also has modes. Only downside could be that it uses Starlock blades like Bosch and Fein. They are less common but you can still find them at lowes and home depot or online. ... show more

  • Yes Yes Yes!! Don’t Wait
Style: Multi-Tool w/2.5Ah Battery
I absolutely love my FLEX tools! I have a variety of them but the multi tool was by far the best purchase yet! I have another brand that works great but once I got this it doesn’t compare! The ease of cut and low vibration makes everything smoother. Super durable and relatively lightweight for the power! It has a variety of functions for all needs but it seriously was night and day better than my other brand. The battery last forever! Definitely worth the money,!8 can’t wait to get more of the FLEX line! Do know the 3D Starlock attachments are hard to find and way more expensive. I did mistake regular star lock for these so I do wish it was more interchangeable with other blades. ... show more

  • powerful saw
Style: Multi-Tool w/2.5Ah Battery
the good: powerful low vibration great battery life the so so : it's damn loud as are all BUT manufacturers can do better they got the vibration down now get the noise down, it does use a different than many other brands blade style though and you need to be aware of it, the starlock blades are a bit more than the "universal" blades and there seem to be adapters out there but as long as i can find generic starlock blades the adapter won't be needed ... show more

Versatile for multiple applications. It is on the heavy side, but the quality makes it worth it. The strong motor makes it great value for the money.
