XtremepowerUS 2200W Demolition Electric Jack Hammer Power Drill Concrete Breaker Bar Point & Chisel Bits Chisel Set

This was the first time I bought a tool like this. Usually, I rent them because I always thought I would have to spend over $500 for a good jackhammer comparable to the ones I’ve rented.I took a chance with this tool for less than $150 and boy am I glad I did. I knocked out a section of 8 ft x 8 ft concrete in my backyard at 4 inches deep with no problem. And now I have a tool that paid for itself that is ready for the next job.Definitely worth it.

Absolutely a Bargain! I have been using this jack hammer for close to a year on various projects at home--breaking up an asphalt driveway, breaking through underground rock, etc. and have never been disappointed. Will it last forever?--probably not, but it should give me several years of dedicated service.The 45 lb. weight is heavy, but manageable. At 73, I can still handle the jack hammer with no problem, but it might not be the case for everyone. The jack hammer comes in a nice heavy-duty case. I ordered three bits for it, but have mainly used the flat 1-ich edge bit.In the fine print of some other reviews, Shell Rotella T1 SAE 40 Heavy Duty Engine Oil was recommended, which I purchased at our local auto parts store. I have yet had to add any oil though. Just keep an eye on the oil level through the small round window.Like most items, a low review is likely due to someone not reading the instructions or not caring for the jack hammer properly. An example: Putting the bit in is tricky, as one has to pull the metal piece on the side of the hammer barrel out and twist 180 degrees in order for the bit to slide in all the way, then pull the small metal piece out again and reverse to the original position. It takes a bit pf practice to master. Once the bit is in, you are good to go. Just watch the oil level. Is the hammer noisy?--Yes, but it is a jack hammer. Be sure to wear your hearing protection.I am thinking of ordering a second of these jack hammers before the prices go up due to the tariffs.

I bought this specifically to break up the bottom of a spa that I intend to fill with dirt. I wasn't sure if it would work, as most of the reviews/videos I've seen are of people breaking up a sidewalk or something, which is definitely not as hard or thick as a pool.Before getting this, I had tried to drill into it and to hit it with a sledgehammer, but the sledgehammer did nothing. I have since read that the bottom of a pool/spa is 8 inches or more, and very hard concrete. As for this tool, when it arrived there was oil leaked all in the case, which was unfortunate. There was no oil in the machine -- maybe that's what leaked out. Strangely though, once I added oil to it and used it, it hasn't leaked into the case again which is a pleasant surprise. The machine feels well built and the two attachments seem very sturdy. I mostly used the chisel bit to break up the bottom of my spa. This size hole took me a good 2 hours, most of the time is just making the initial hole.. once you've hit dirt, you can fairly easily branch out from there. If you're new to jackhammering, watch some videos on it, and don't be tempted to try to stay in one spot and bust through it all at once, the bit will just end up getting stuck. Which happened to me many times, and I just used the other bit to break up the concrete around the stuck bit... so it's a good thing they included 2 bits.All in all this is a great tool, and a great value. I could not have done the job without it. I think it may also be useful in the future for digging in rocky soil.

Likes: The price is certainly a big selling point. If you shop around for demolition jack hammer, this is one of the most affordable product. It appears to be a fairly sturdy piece of equipment and would be suitable for most DIY projects.Fairly decent performance as a jack hammer without being too heavy or unwieldy.DISLIKES: Upon opening the box, this item raised some serious Red Flag for me, not because of the actual product that I bought but because of the accessories and technical manual included. Here are my issues:1. The mask, gloves and eye protection are totally CRAP! (See pictures above. The gloves will probably fall apart within the five five use - Note that the cloth material is so thin and flimsy that light is shining though. The dust mask filter appears to made of a single layer of cloth. It may be good for a single use. The eye protection is already deformed and disintegrating before I even took it our of the plastic. I would definitely not recommend using these to protect your eyes and they are definitely NOT OSHA approved eye protection.2. The tech manual is also CRAP! See sample page above, which is suppose to detail critical parts and inspection areas but are so confusing even with pictures. If you have used a similar type of equipment, then you might be able to find the inspection areas like where the carbon brushes are located. But this manual will not help you.I was able to find the type of oil that I need to use for this product by reading through some of the comments and answers to questions here BUT I couldn't find it in the manual itself.So why point out these issues that are not directly related to the product? I point them out because it also represents the culture of the manufacturer.Yes, the product itself, seems to be a decently manufactured product that worked well when I tested it, but the question now is how well will it work in the long run. If I was buying a Makita or a Dewalt, then I wouldn't even be asking these questions. But obviously I chose these product because of its much lower price. However, even with a lower price, I still have the expectation that this product will remain serviceable for a long time.So the concern that I have with the manufacturer is why did they even add three accessories of such low quality that it raises the question of their own product quality. Yes, on the initial buy, the addition of the gloves, mask and eye protection may have provided an added selling point. But after seeing the accessories that they delivered, it was very disappointing.For now, I am keeping the jack hammer (while throwing away the gloves, mask and eye protection). I think the product delivers for its price point but I can't help but be skeptical of its durability. Only time (and use) will tell if this buy is actually a good buy.For now, 4 stars.
