Review: Light and Cuts Very Well! - As a woman that was looking for an easier way to do lawncare this year, I opted to buy this because it's light and simple. It has two speeds, one normal and one more powerful. I trimmed grass along my fence mostly, so it cut that with ease. It also cut through thicker weeds well too. I did not experience any weakness in this tool unless the battery was dying. I love that the length is very easily adjustable for use and storage. It also edges pretty well, however, it will use up a lot of the battery. It also can be used with other Black & Decker batteries, so I was able to use my hedger batter with it. I will say, I do think these batteries may be a little weaker than my old ones. Regardless, the product works well and was a great value for the money!
Review: Perfect for around the house. - I had the previous model and it lasted a long time. I decided to get another for my in-laws. This isn't anything heavy duty, but it does the job around a normal house. The batteries last about 30-40 minutes which is enough for one house. The string spool is easy to replace and also lasts a few months, if not the whole summer. The length is good for me (5'9"). It's pretty quiet compared to gas and doesn't weight that much. The value is fair. You could go cheaper or more expensive, but I like this quality and power with weight.

### ⭐⭐⭐⭐ 4 year's use: works great, but had to repair the push-button mechanism
*by N***8 on July 4, 2023*

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.)
