Ligera, no necesita cable de alimentacion, solo si el pasto es muy largo o una superficie grande vas a requerir varios dias, o mas pilas. Viene con dos pilas, tardan unas 6h en cargarse y al ajustarla en la segunda velocidad (para cesped largo o espeso), dura cada pila unos 20min de trabajo ininterrumpido. Linea de corte muy facil de montar y avanzar.

Fácil de utilizar para ser principiante.... excelente que traiga 2 pilas

I bought this to replace my 15 year old B&D trimmer which finally gave up. It uses the same string cartridge and the last B&D was very reliable, so I stayed with the same brand. This one is lighter and the string feeder, both automatic and push-button when needed, are working great. I have a quarter acre lot with a long driveway, multiple beds, and a sidewalk which all need trimming. Running at the higher speed has not yet depleted the battery, so considering it comes with a spare, I can't envision running out of battery life. I particularly like the wheel which allows you to rest the trimmer on the ground when edging upside down, and it really helps because you are not suspending the weight of the trimmer to do edging. It also works well to space the trimmer from walls or fences when trimming around them. The only assembly is attaching the guard. A note on that: the guard has 2 little wings that slip into a slot, and then one screw. I had a hard time aligning it and nearly broke the tabs, so I recommend looking closely at it and once you have it lined up right, it clicks right in. I was aligning it incorrectly, which is my fault, but I can see someone breaking it as I almost did. So far, works great and nice to use the B&D trimmer cartridges I already had and not spend extra money on those. Would definitely recommend, esp at this price point!

This string trimmer works as well as any, I suppose. The two batteries that come with it are small and require recharge too soon. So, I bought a larger off-brand battery that lasts a lot longer. Because the charging takes so long, I recommend that anyone who has significant trimming to do should buy a larger capacity battery. ( I have not looked into whether a fast charger exists for these batteries.) The ability to quickly change from horizontal to vertical trimming position of the "working end" of the trimmer is very convenient. So, basically, this is a good trimmer that comes with small capacity batteries.But, one big flaw for this trimmer (and possibly for other brands as well) is the design of the trigger mechanism. Over time, I noticed that it was getting more and more difficult to press the trigger after having depressed the safety switch. (The safety switch, by the way, is a real pain -- in all of these type tools. There should be a way to bypass it.) The trigger seemed like it was getting hung up, and I had to bang the working end on the ground while trying to depress the trigger in order to get it going. Finally, I could not get the trigger to start the motor, no matter how hard I depressed it. So, I figured I'd take it apart and see what was going on with the switch. Easier said than done. I Googled how to repair the string trimmer, and found a Youtube video that showed how to take a similar model apart. The problem I had was "how to remove the handle" -- which you must do, in order to take it apart. The handle is made of a very resilient plastic that has a slight "give" to it, and you must force it off of the unit. (I had been afraid that it would crack/break if I did that -- but, that is what you have to do.) The video also showed that the plastic trigger mechanism gets worn, so that it cannot allow the lever to travel far enough to push the microswitch. This is the key to the whole problem: The plastic lever gets worn over time. The solution: file the worn area so that it is smooth again. It is a simple fix -- but, it would not happen if the lever were made out of a more durable material.So, there you have it: If you are having trouble with the switch trigger-- look up the Youtube that shows how to fix the trigger. Also, be aware that when you put it back together, the spring that allows you to move the head into the horizontal/vertical positions must be positioned entirely into the "large space" and you will not be able to close the two halves of the unit if that spring is not positioned properly (Trust me: I spent a lot of time trying to get the two halves closed together.)

Great b&d trimmer. I had a previous corded one, I found this one was heavier. I liked the wheel allows a more precise edging. Would have been nice for the batteries to have an indicator rather than just dying out. Otherwise would buy again

I love everything about this. The battery lasts along time. I can do my front and backyard on one battery around fences, little kid toys and play structures. I have a average sized in town single home lot.It's very light, I do it myself. Everything on this unit is easy to use, no messing with cords or trying to pull start it 79 times. Just click the battery in and go. I always charge the battery right away after each use so it doesn't dissipate. It's very adjustable for tall or short people. Pretty strong , I've taken down some monster weed/trees. I'd recommend this to anyone young or old. It's light, and user friendly! I actually look forward to using it after mowing.

Solid 5-stars on this one. This weed whacker is hands down the best I've ever owned.Battery/ies DO come with it.Fairly solid construction - it's got plenty of plastic pieces, but they aren't too flimsy or easily breakable.Battery power and life are excellent. I've got a small to medium-sized yard with a fence around it, and one battery takes care of it all. Just in case it were to run out, the second battery (which comes with, if you choose that option) is on the charger.There are two battery "modes" - power and battery life - and they do exactly what they sound like. Power mode gives you more cutting power (at the expense of battery life) and battery life gives you longer cutting time (at the expense of cutting power). I've found that the vast majority of my weekly weed whacking needs are taken care of using the battery life mode. You can quickly and easily switch between the two modes if you need a little more oomph.Battery runs about 20-30 mins (of actual cutting) on the power saving mode, a bit less on power mode. If you find you need more run time or power, you can always upgrade to higher capacity Black+Decker universal battery (available at hardware stores, Amazon, etc).As for the string/cut wire, there are easily-replaceable pre-loaded heads that simply click into place. From what I've read in other reviews, there are ways you can string it yourself with whatever string you like. Personally, I'll stick with the pre-wounds - I'm 3 weeks into this product and still using the first pre-loaded cartridge that came with it. Plus you can get a three-pack of replacements on Amazon here for about $9 (product number is AF-100-3ZP).The product description doesn't say this unit has an auto-feed feature, and says it has a button on the handle that releases more string; the button sure does work, but I've found that the unit seems to be auto-feeding itself most of the time too. I've rarely had to to "tell it" to let out more line. It's been quite convenient and thus far hasn't tangled or anything.Additionally, the unit can be extended to make it taller/shorter. You just twist the lock, shorten or lengthen as-needed, and twist the lock back into place. Very quick and simple.There is a "safety" on the handle that you need to hold down with the side of your thumb before you can pull the trigger. It's very conveniently placed and doesn't make it hard to use.My only minor complaint with this unit is the handle (the one mid-way down, not the one with the trigger). It functions just fine, but it's got "lock" points (to set the angle how you like it) that occasionally come loose. It has to be set to one of these three lock points and sometimes, if you've been using it awhile, it'll vibrate out of the lock and slip to the next one. Takes all of about 2 seconds to set it right again, so it's certainly not a deal breaker, just a little annoying when it happens.
