Great little router with plenty of power. I bought it specifically for a job to hang a bunch of doors. Being so small and light makes it much easier to control when using on jigs to mortise for hinges and strike plates. I recommend making a larger base for it, as the factory, round base isn't quite big enough to stay flat on top of most hinge mortising jigs. I also recommend plexiglass/acrylic so you can see through it. The LED light is a great feature and is very bright. The safety 2-button power switch is also a great feature. Some may not like having to press two consecutive buttons to get it to start up, but a simple rocker switch would be too easy to accidentally turn on. I bought and installed the optional dust collection port, which I highly recommend. It captured at least 95% of the sawdust produced when routing. The only thing I don't like about it is that the collet seems too difficult to tighten. It does tighten using the two wrenches provided, but it just seems to need way too much pressure. Having said that, this is my first, small trim router, so maybe that's just how it is with the smaller collets. I'm used to the large collet on my full-sized 1.75HP router which is much easier to tighten.

The battery / charger starter kit is a great launch point into the Makita 18v cordless tool platform. These 4 AH batteries have plenty of power to run a drill or impact driver all day and provide adequate runtime for some of the higher demand tools like a circular saw or even the 10” chainsaw. The fan cooled charger provides good charge times for the batteries as well, keeping them in the best operating temp range. The canvas carrying case is a nice added bonus and is a good size to carry a tool or two along with some accessories.

This is a review of the Makita 18-Volt LXT Lithium-Ion 4.0 Ah Battery and Rapid Optimum Charger Starter Pack. This is a nice kit, since I have another kit that requires more batteries than come in the kit. Another charger is going to come in handy too. This charger works pretty quickly. I was a bit surprised by the internal fan of the charger, as my other brands don't have that. The LXT batteries are nice, since they have some great run time. This kit came with a bag. Not really sure why.

This is a great starter pack or an addition to your supply of Makita batteries and chargers. The kit comes with a nice storage bag to keep them clean and helps to keep them organized for easy travel too. The batteries will work with any of the Makita LXT 18v tools and there's a lot of them.The charger works with any of the 18v LXT batteries. With this combination, it takes 30 minutes to recharge each battery. The charger is fan cooled and allows the batteries to be charged fast and at their top performance. The design makes swapping batteries easy and fast, yet firmly locked into place. Extra batteries and a charger are always great to have around. I'll even use these in my chainsaw.

Great router. I have two other cordless routers,from different companies, so for me to get a third from a third brand meant I saw some must have features. 3rd time was definitely the charm. I mainly got this for one reason. Anyone ever use a router would know you will definitely need a mask on as it spits out dust out, the dust port was the main reason I got this. I am a righty and using the right going from left to right with the vac attached to the port was a little inconveinent. You would have to hold the router so the back is facing you, making the window to see your work piece useless. I simply put the vac on the left and this resolved that. The rack and pinion for the microadjustments is quick and easy. I knew exactly which way I was going each time. The router was not loud at all, to me. My sound meter showed 79 db, with the router operating on its highest setting on a piece of mdf

Best cordless router to date by a WIDE margin
Routers may be my favorite woodworking tool, and this router is one of many great reasons Makita is far and away the best platform for woodworkers looking to up their game. Most manufacturers don’t even have an answer for this thing. At the time of this review only 2 competitors offer a cordless router (which are almost identical to each other) and neither of them happen to be yellow or red. But it doesn’t look like Makita took the relative absence of competition as an excuse to slack off and give us a mediocre product. This thing oozes quality all over, and is thoroughly well-designed and -executed. The wood clearing and lighting in particular are AMAZING! Completely blows the competition out of the water. Just hook up a competent vacuum and go to town! No more inhaling woods chips and struggling to watch your cut progress through saw-dust coated safety glasses! It’s so effective I can literally just throw a tarp down in my living room and go! I’ve seen it claimed this unit’s depth adjustment doesn’t have a “fine-tune” feature. Not sure how that claim stacks up because high precision with this unit’s depth adjustment is really completely trivial: just partially engage the latch until it develops a little friction, then finely adjust the rack and pinion as desired, and fully engage latch when it’s where you want. The aluminum housing is precisely machined and marked such that you can easily use this technique to adjust to fractions of a millimeter. So easy and there’s no play or slop! Keeping it real: this unit will not match the power levels of some large cordless units. I’m not of the impression this was a particularly significant design goal either. It is made to primarily use 1/4” bits which I think is a good indication of where Makita aims this unit to be used. For me, I’ve been too giddy about the dust clearing and superior visibility to pay attention to whether or not I’m going any slower than with my corded unit. I’m holding onto my old corded lug and all its 1/2” bits for now, but my feeling is with the Makita’s drastic improvement in cleanliness, fantastic and completely irritation-free visibility, and go-anywhere convenience I’ll be more than happy to shed the old corded unit before long. Between all those factors plus the simple convenience of not having to maneuver around cuts trying to avoid damaging a stupid cord I’m probably getting my work done faster (and more importantly with better consistency and precision) if anything. Did I mention these Makita units can attach to their compatible plungers as well as several other attachments already available for their corded models? No need to wait for peripherals to be released because they’re already all out there! This unit is a godsend.
