I like to write reviews that answer some of the questions I had before buying. Here are a few things that you may want to know.

1. This tool does not come with the battery or charger, all you get is the tool and the hook with the screw.
2. The hook is akwardly large and can not be hung on a belt very comfortably, ( Who uses this with a belt though ).
3. The switch is in the back of the handle and is sort of concealed, I at first thought my unit was broken because LED didn't come on when I pressed the switch.
4. This unit willl almost certainly require a pin or something like it in order to take off the impact sockets that have holes for the "bump?"
5. This driver works best with the Impact rated sockets and can break the chrome ones, I've tried both.
6. This tool is definitly heavier than Makitas impact driver for screws, still a tool easily worked with 1 hand above your head or elsewhere.
7. The tool requires the 3.0 battery and runs for about 15 or so 8 inch by 3/8 thick lag screws in to wet treated wood, after that its starts getting slower, still completely reasonable run time matches or better than makitas circular saw with same amount of use.
8. Lug nuts are not a problem as other have stated.
9. People have voiced concerns that the bottom peice moves up and down slightly, it really does and is supposed to, the tool is heavy and dropped from a height will easily break the battery without the dampening. This movement is ever so slight does not move on its own only when you use some force with your hands. Props Makita!

I bought this to change tires at the race track. But I just keep finding uses for it. Tons of power for a cordless and decent run time on the little lithium batteries. At first the little batteries do not fit, but there is a ridge in the tool there to force you to use the big batteries. All you have to do is grind it off and the smaller kit batteries will fit. Works great for: driving in big lag bolts for a deck, changing a flat tractor tire in the middle of a field, swapping car tires.

What it does lack is variable speed, but this is a brute force tool anyway. The little led light is handy too. FYI, at the track, one battery will do almost 2 sets of tires tourqued to 100 ft/lbs.

I purchased this solely for removing the 1 1/8" pinion nut on a 15 year old Jeep Cherokee. They're torqued from the factory to 200 ft-lbs. In MN, the salty roads lead to a lot of rust on threaded fasteners, so I was worried about being able to remove such a large, heavily torqued nut.

This impact had absolutely no problem getting the nut off. 2-3 seconds of hammering and off it came. For anyone who lives in the rust belt, buy one of these immediately. I wish I had gotten one sooner, it is SO much better than a 2' breaker bar with a pipe over the end of it. Plus it's still small enough to get into most places.

It paid for itself on just this one repair as the local shop quoted me ~$250 for this fix.

For anyone who frequents junkyards, this tool's value is immeasurable. Taking apart rear ends or suspensions is absolutely no problem, though I recommend an extra battery.

Cons? It's a bit heavy, especially at arm's length, but it removes nuts and bolts so quickly that you don't have to hold it for long.

By WI DIY'r on November 3, 2009
I hestitated to buy this as I've heard stories from friends that many of these beasts don't have much torque to them. Well, I shouldn't have waited, this model is pretty much what I was hoping to get. It's got great battery life and plenty of torque. The ergonomics are good, but be pre-warned about the weight of it, it's pretty heavy. It's built like a tank, and I guess that I wouldn't want it any other way. It is easy to use, although the toggle switch to power it does take a few minutes to get used to. The first few minutes of using it, I found myself not paying attention to which way I was pushing the toggle and going the reverse direction to that which I intended. That was my stupid mistake, with any new tool you need to pay extra close attention to it the first few times you use it.

Edit to add that if you are working on some very tough/tight bolts, make sure that your battery is fully charged. These batteries are not supposed to show that property, but apparently they do when pulling a heavy torque. Well, at least I'm seeing it. I'll have to check the manual again to see if it mentions that.

* Extremely powerful, comparable to many of the best air-powered impact wrenches but without the hassle of a hose.
* Uses Makita's super lightweight 18V lithium battery.
* Forward and reverse are built into a single trigger. The top of 1/3 of the trigger activates reverse, while the bottom 2/3 operates the wrench in forward. No need to press a switch or button before changing directions.
* Seems very wellbuilt: Has a shock absorbing base to protect the battery, solid feel, and sockets are easy to change.

* It's heavy - plain and simple. Although that is probably to be expected from a powerful impact wrench.
* It is unbalanced because the top is so heavy while the battery is very light.
* Dual-use trigger takes a bit of getting used to (but is a better design once you've done it a few times).

Overall, this is heavy-duty and efficient unit that makes a good addition to the already outstanding line of Makita LXT tools. We use it for lawn mower repair in my landscape business, and it is definitely the preferred tool. It would be great for automotive work and will spin the lugnuts off of a verhicle in a flash (we tried it on a trailer wheel).
