Every once in a while when it warms up it gets stuck just pick it up hold the trigger and smack the tool end on the ground works again for about 5 min

Does what it should. You will need to buy extra hydraulic oil (can be substituted with motor oil but don't tell anyone I said so) if you use it for 30 minutes straight you will need to avoid touching the body...gets really hot. Otherwise, for small jobs it's good

I bought this hammer to help demolish a 70 year old concrete stoop that was covered up by a deck. It had pulled some of the brick away from the foundation and needed to be demo'd by hand instead of with a skid steer to make sure the house didn't also get wrecked. I borrowed an Echo diamond saw from a friend which allowed me to cut the tough old concrete into 6-8" long pillars. With the hammer and spike attachment, I worked as big of a chunk as I could off at a time in order to make cleanup easier. Working sideways under a deck with a 40 pound plus tool was tough and sweaty. The hammer DOES get hot with use, so it's best to work in spurts and then let it cool off. Also did I mention it is very difficult/hard work. The front handle is the best place to push into the target to reduce vibration into your body, however, it's more accurate to hold by the main shaft. Vibration damping gloves might help, but I didn't use them because it was so damn hot and I was switching back and forth from saw to hammer. The spike bit has lasted well. The skinny chisel bit I started with and it got dull before long. The wide chisel I barely used to try to get mortar off the brick wall. For this job, it was an indispensable tool. I think a good value, especially since I got it on sale. The cord seems a bit undersized for the current it's drawing. But it didn't cause a problem for me.

I did a video review for the 16inch electric saw and the electric jackhammer.

Used many hammers in 40 yrs of construction 2nd to none . Bpm ,force of hits excellent Never would have thought that @ that price

The product looks good an very very heavy but the case was delivered broken, that I think its a problem from delivery

Top rapport qualité-prix ! Ce marteau-piqueur envoie du lourd pour pas cher — il casse le béton sans broncher pour les petits et moyens travaux. Prise en main confortable, changement de burin facile, et il tient bien la route pour un usage occasionnel. Parfait si tu veux du costaud sans te ruiner. Ps, j’ai fais 150m2 de béton non armé et de cailloux, le tout sur groupe électrogène .

Leaks oil after some use. Not sure if it’s the o rings. I put more oil in and it keeps going. Besides that hits hard light a good hammer does!

Decent unit for home use. Just put thicker viscosity oil in it than it comes with. Developed a small leak but not to bad. Essentially cheaper to buy this unit than to rent one. Removed a 12'x70' slab that was 2 feet thick in spots.

I am pleased with the tool. It works well, but the consumable chisels do not fall into the Vevor category of "tough tools". Hence, 4 stars. I used the jack hammer to break up some Precambrian igneous rock. After about 2 hours of hammering, the tip broke off the flat bit and, after about a half hour more of work, the tip broke off the point bit. It was normal use, for the normal "Intended Use" of the Jack Hammer, according to the User Manual, includes "stone without limit of the dimensions of the Piece to work". Otherwise, the tool works very well and I am pleased. I have the tool that will let me leave my mark on this mountain top! On a whim I submitted a warranty claim for the bits... If you do the same, this is what they'll say: "We regret to inform you that the chisel is a consumable item. Once damaged, you will need to purchase a replacement." Amazon sells them (CCTI Concrete Chisels). Too bad Vevor doesn't sell individual chisels. I would order replacements from them. I like their service.
