JUST WISH IT SHIPPED WITH SMALL BOTTLE OF CHAIN OIL AND HEDGE TRIMMER LIGHT WEIGHT OIL. The pictures say it all. What is used to look like. To what it looks like after my new Milwaukee edger got a hold of it. Still have not tried the string trimmer, pole saw or the hedge trimmers. Do to, now having too go back to the store to buy some. I ordered this set online. Not thinking about needing oils. Being most items in the past have come with a starter bottle. I did purchase the blower separately and that was Nice and Light. I did also purchase a hight output 3.0 ahu extra battery as a back up. And to use with the pole saw.

    The trimmer exceeded expectations. Was very hesitant in buying it due to the price, but after biting the bullet and getting it, I will never go back to a gas powered trimmer ever again. No hassle, string loads easy breezy, quiet, battery life so far barely uses 1/4 of life on my whole yard that requires a good bit of trimming and edging. broke down and decided to get the edger and hedge trimmer attachments. If they work anything like the string trimmer, my yard will be the easiest its ever been. Now I just need Milwaukee to come out with an electric ride on lawn mower!

    In turtle mode it works really well, saves the battery and is strong enough to cut normal trimming. In Rabbit mode it is more powerful than my high end gas trimmers. I have gotten rid of my gas trimmer because this one is so much better. One battery will last for my entire house and the second battery will cover everything else.

    Been holding off making this purchase for over a year. Finally bit the bullet and bought it. Blown away. Handles all the trimming around the yard and enough juice left over to edge around the driveway and street frontage. Even more impressed with the line that comes with the tool. Holds up great.

    1st and most importantly is the thermal shutdown feature. I will get about 10 to 12 minutes of moderate to lite use on the low power setting before it shuts down and needs at least 30 minutes to cool down for another 12 minute run. This is taking down some high grass about 18 inches using a 12ah fully charged battery. While the unit does its job well, especially on trimming very small areas (around trees and flower pots) the run time limitations on are quite disappointing. 2nd is the rather strong vibration that the unit produces while running free under no load which only increases under load. It is the same or perhaps even a bit more pronounced than a gas trimmer. Granted the noise is much less than its gas counterparts, but my hands are going numb from the intense vibration produced after just 5 minutes. 3rd is the trimmer head angle. It should be a bit more acute. Especially if you are on any type of slope. It seems the head is almost at the right angle but not quite, requiring you to hold the unit at an uncomfortable difficult angle to achieve the desired trimming effect. 4th is the way it chews through battery's. Granted I can recharge them more often than you would expect because I am hanging out waiting for a half hour for the motor to cool down. After about 8 minutes of use on the low setting a 12ah battery is down to 2 bars. Switch it to the high setting under a lite to moderate load you will get about 5 minutes of use before either thermal shutdown or battery exhaustion. A 9ah battery fares even less well. This doesn't seem very heavy duty to me. 5th is the safety lock on the throttle. Its awkward and rather uncomfortable digging into the webbing between thumb and index finger while the motor vibrates like an out of balance washing machine. I'm wondering if something a bit more ergonomic couldn't have been designed? 6th is weight to power. I don't know if it is a close class comparison but my gas trimmer is a Husqvarna 525L which comes in at 9.7 lbs to the Milwaukee's 9.85 lbs. After battery and charger both come in right at the $300.00 mark. But Lordy that Husqvarna is a workhorse beast. Like I said I am not sure if its an equitable class comparison but they are similar in weight and cost. NOT power and certainly not runtime. I have not in my limited use experienced any issues with the bump feed head so many other reviews mention, and this seemed to work flawlessly on my unit. I really do enjoy the fact that it has an extension to give me a bit more reach as well. It has made a steep section of my property line much more manageable. If only it didn't take me 8 hours to cut what I can do with a gas trimmer in one hour. I am open to hearing from Milwaukee on any of these issues, especially the thermal shutdown problem. Most likely I will be returning this unit. It just doesn't meet expectations.

      fantastic pro tool
      I absolutely love the possibilities of this tool!! Specifically; I have the string trimmer which has been an integral tool to my lawn maintenace and has left me extremely impressed with the quality of this tool, but it is noteworthy that there are other LOK attachments for the base of this tool, including a hedge trimmer, edger and chainsaw pole attachment. This tool is of professional quality, has no exhaust and is much quieter than its gas competitors. It lasts considerably long for a battery powered tool and is much better for my health - for my hearing and my breathing. It is also much easier for me to like this tool as I already have several tools on this platform. Definitely reccomend! I am keeping my fingers crossed for more amazing tools from milwaukee, such as a sweeper /snow thrower LOK attachment would be amazing!

        Overall I like this product. I had my Echo gas 2 piece system for 17 years. This battery system can definitely hang with the gas system. I was skeptical as many are when switching from gas to battery. But already being a Milwaukee hand tool guy, the switch made it much easier. Pros: I LOVE not dealing with gas. I like the quick start up. As most have stated. It will do just fine in turtle mode when just doing a yard that is already manicured. Jump to rabbit for unkept spaces- no problems. I also got the edger attachment. Same applies for that but I usually use the rabbit just to finish quicker. It is pretty well balanced. Battery run time is good, not great. Definitely runs way longer when just using turtle mode. It is nice that I have 5.0 Amp batteries from my hand tools if I run out of battery in the middle of a trimming. Cons: I do NOT like the trigger. It is variable speed but I feel that it is stiffer than it should be and after trimming for about 10 mins, my fingers start to hurt a little. Not unbearable but uncomfortable. Shaft length- I feel that the attachments could be an inch or 2 shorter. I am 5.10. So not sure if that makes a difference or not. Lastly, I do NOT like the thickness of the string trimming head itself. I know that they made it that way to hold more string. However it makes it hard to trim places all the way to the ground (concrete driveways etc). More compact would be better. I did make two modifications that help me out. 1)First thing I noticed was that the "arrow" attachment sticker for the actual attachments are NOT aligned very well. The second time I was used it I did not fully engage the attachment. I thought it was broken until I realized what was happening. So reattached it fully. Then put a piece of color electrical tape on it to let me know that it is fully engaged. 2) I DID NOT like the fact that when you put the motor head on the ground that there was NOTHING on the bottom of the motor casing to protect it from getting beat up and damaged. So I had some of those dense felt pads you use on the bottom of furniture so that you do not scratch the floor. I put some of those on it. Both mods work great. OVERALL: I like the product and would buy again. I just guess that I will never understand why simple things are not thought through during R and D before production. It is the common sense part of me shaking my head. The trigger and head thickness are why I took one star off of my overall rating.

          I intended to buy yet-another gas trimmer, but saw this M18 FUEL. Though I own an electric-car, I never thought this electric trimmer could compete with gas. But, since every Milwaukee M18 FUEL tool I own has been pure-perfection, I gave this a try... This trimmer is nothing short of outstanding. Instant-power and instant-torque like you'd expect from an electric motor. The string-winder head is simple to reload and outperforms every trimmer I've ever owned. I am thrilled I smashed my gas-trimmer into 20-pieces (after running like crap FOR THE LAST TIME) and bought this M18 FUEL. I spent half my time clearing land just trying to keep my gas trimmer operating; this electric M18 just flat-out works all the time. My only (minor) complaint is battery-life. Their specs of 1-hour runtime is wildly-optimistic. I averaged about 20-minutes under heavy load with the M18-9A supplied battery, but those 20-minutes are flat-out hard work. I got about 10-minutes of heavy load operation with all of my M18-5A batteries. That said, I have enough batteries that I operated this trimmer non-stop for 2-hours straight, in knee-high thick field-grass, using it more like a brushhog than a simple yard-trimmer. This trimmer took everything I threw at it, and just kept chugging, outperforming any gas-trimmer I've ever owned/abused. I love every M18 Fuel tool I own... impacts, drivers, drills, cut-offs, grinders, flood-lights... just-awesome.

          The weed eater was easy to assemble and very strong. I have the 12.0 battery and have cut my grass 4x since having it and it still has 2 bars left.
