They work great with my impact driver

Took me a bit to figure out the magnetic thing. My biggest complaint is how you have to slip the bits back in to their places. I prefer them to push and snap in. I'll live with it though. They work great with my impact driver.

Great impact drivers that last a long time to daily abuse and use. A really great price, so I got 2 sets for a little less than the home improvement store prices for 1 set!

This is a solid choice for impact driver. I'd say it's slightly overpriced but it is light, powerful, and holds a charge. I have the drill so this was to match the set. I really only needed the driver but opted for the kit since you can never have too many batteries. Hitachi makes good power tools.

Even with the joint socket, there were a few areas that my impact gun was just to close to.
These fixed that and work really well with it even on the rust covered bolts.  ^_^

Works great. I use it all the time in my impact driver and have no issues. Bits tend to be slightly tough to remove at times but that's much better than the alternative.

I have been using these for quite some time now and they are standing up to the beating that impact sockets are expected to take.

I use these with my BOSCH 12V Driver and Impact Driver and they fit perfectly.  I also use them with my DeWalt and Milwaukee cordless drills in a standard chuck.

The bits are of high quality and they fit both Philips and Square Drive screws securely. I have driven over a hundred screws so far and the tips show no signs of wear so I'm expecting  a lot of life.

 Having a bit on each end is very clever. You are getting two drivers for the cost of one.  It also means I don't have to carry a spare set of drivers. If the driver is damaged I can just flip it around and keep going.
I'd also like to see units made with a #1 Philips and a #2 Philips on opposite ends. And while they are at it a small and medium flat blade for those slotted screws that are still around.

Awesome set of drills. When I was shopping for a new drill I was not looking to get 2 of them, but found these to be a good deal. Also, I had never used an impact driver before, but now I don't know how I lived without one. The impact drill is amazing. I use that 99% of the time. Its super powerful for being so compact. I drove about 40 outdoor wood screws when repairing a fence and each one went in like butter. The battery seems to last forever too. After the fence repair I used it about 4 or 5 times after that and it was still about 75% full. The hammer drill is great too, but the only time I use the hammer drill is when I actually have to drill a hole. All other tasks are now handled by the impact driver.

If you've never used an impact driver before, do yourself a favor and get one.

Received these bits today. They are still have no detents, but they work fine in a drill for driving prescribed nuts and bolt heads. Yes, if they had detents we could use them in a power screwdrivers and impact drivers (1/4" hex chucks), which would be a plus. Nonetheless, they get the job done in a drill chuck. When the company makes the same set in a detended shaft, I'll pick them up, too. Reasonable price and product in addition to my Dewalt nut-driver set (it has detents but not the spread of standard and metric sizes). Detents would have made Tekton's bit set a five-star item for their overall application in 1/4"-hex and standard-chuck power tools.

I have multiple sets of these, they work excellent and have a substancial longer life then standard bits when using an impact tool. Don't buy them if your primary use is with a drill/driver, they are hardened to take the pounding that impact drivers/wrenches give them. For use with a drill/driver stick to the standard type bit they are a little softer and grip better in that use, But if you use an impact and have experienced the breaking of standard bits - these are the best.

these are great for little impact drivers - but - they don't last long but at 10 bucks you can buy 3 !

These work as advertised.  They're sturdy, they're a great length for getting into some hard-to-reach spots on my RC cards, and they snap in place nicely in my little 12V impact driver.

Holders for the extra 2 bits would have been nice, or some sort of case.

This impact driver worked as it is supposed to. Used it to remove rotor holding screws on Honda Civic. Took a couple of hard hits and eventually freed the screws. No drilling. Great time saver.

works great don't use it in an impact driver! drill with torque adjuster its plastic and will strip out. mine did but you can still chuck it in a 1/2 in drill

Its been a year since I bought them and honestly they are the best tool I have I use these on a dewalt impact driver and I have managed to take lug nuts of of cars the max has been 150 foot pound of torque but that's the drivers fault. I had a pare of craftsman's adapters and they all broke these have lasted a year and I haven't had any issues yet.

Good price, prompt shipping.  I love the little impact driver.  It is sure to become one of my go-to tools.

Great deal on a drill/impact driver combo.  Tools work as expected and the lights on both tools are very useful. Plenty of battery life for both tools help this every-so-slightly handy man knock out the to do list in record time.
