Electric Suction Cup for Glass, 9'' Digital Display Suction Cups 580lbs Max Load, Automatic Vacuum Adsorption, Digital Motorized Suction Cup, Glass, Tile, Granite, Metal

While the battery life isn't AMAZING, it's still pretty darn good. Highly recommend if you move countertops or large format tile. The USB-C was a must for me

Got this to help move a 400lb safe. It would have been impossible without this. I got the safe onto a furniture Dolly and used the suction cut to push/pull the the setup through the house and into the final location. With some help I got it off the Dolly and then managed to adjust it to the final resting spot and it definitely would have been 50 times harder without having a handle that could be repositioned as needed. Amazing tool! And I plan on using it for other jobs in my shop as well. Moving plywood, tools, tool boxes...tons of options.It's easy to setup, one button operation, comes off easy to move it and the price is really good. They hold amazing well. It's like it's bolted on once it's fully vacuumed on. It holds like 500lbs. And I believe it.I want to buy a second one for really big jobs and eventually get a carrying case for them to keep them safe. I suspect they're a bit fragile because they're electronic, so don't drop it, but they are very sturdy and well made!Very happy with the product and absolutely recommend.

Tested this by sticking it to the hollow metal flush door in my barn and left it there for a couple of hours. Over that time it did loose a little suction according to the display, but not enough to trigger that auto top off that it says it will do. I work in the commercial glass industry so we use suction cups daily to carry large pieces of glass and have huge multi-cup rigs that we can hoist glass weighing thousands of pounds into the air. The quality of this cup seems pretty decent. Two issues and why I docked a star (probably would have docked 1-1/2 stars for these if I could). In the title it says "580lbs Max Load" but the digital display on the tool is only in metric and I can't see any way to put it in lbs (instructions don't mention anything). Would have been nice to know it was only in metric. Not a huge deal, still totally usable, but a little irritating. The 2nd item is this is the first suction cup like this I have bought (and I have bought hundreds of them, many from Amazon just to test them out to see how they compare to the commercial models we buy at work) that didn't come with a plastic case to store it. These cups stop working if the cup gets dusty or dirty so it is important to not set them down on their cups when using and also to properly store them in a plastic case by themselves. The instructions actually mention putting the cup into its blow mold case. It only comes with a zip lock bag, no plastic storage case. To me this is a big problem. The instructions mention a removable battery, but I haven't figured out how to remove it or if you can yet, the instructions do not show how to do this unless I just missed it. Without having a spare battery it doesn't really matter. This charged via USB C and comes with a cable without a plug.

Buen agarré, buena duración de la batería y fácil de cargar ya que tiene una entrada para cargador tipo c, en detalle que ami en lo personal no me gustó es que tarda mucho en realizar el vacío (parar de succionar)

The media could not be loaded. High suction, larger suction cups can hold larger objects.The white bottom not leave traces on the glass. Easy to use. Greate.

The SHIJING Electric Suction Cup has definitely impressed me with it's strength, quiet operation, and it's quality.I frequently have to move larger items that are sometimes unwieldy to handle and I discovered some time ago that suction cups like these can make this task much easier. I wish I had discovered this sooner as it probably would've saved me so much time, frustration, and back pain. But, now that I have found the suction cups I'm even more impressed by this battery powered version that's intelligent enough to monitor the suction being applied and increase it if it's necessary.I decided to test this out before trusting it on some important, and heavy, items. First thing I did was check out exactly how good this is and are the weight claims accurate. After attaching it to a painted wall and hanging from it, then adding more weight and hanging on it again, I'm pretty impressed. I even decided to get my workout in and tried to hang from it as long as I could, it never budged an inch, or a fraction of an inch. Next, I loaded up a container and hung it from the cup and left it there overnight. Next morning, it's still there and in the same position, it hadn't moved an inch, again!That was enough proof for me and I started to use it to move those unwieldy and awkward items I spoke about earlier. It immediately became my go to tool for such items, and more. So much so that my friends and neighbors noticed it and started asking to borrow it. Now it's the go to tool of my community. It's like "hey I need the suction cup, can I borrow it" and "Do you know who has it?" "I think Bob has it, or maybe Mark", on a lot of days.One thing I thought was an oversight is that it didn't come with a case. With things like this that require a clean and preferably flat surface to store it is a necessity. The simple plastic bag it arrived in is not going to work for a beautiful piece of equipment like this.Overall though, this is a very impressive tool that I'm 100% glad I ordered. Would I order it again should the need arise? Yes, absolutely and without a doubt. Would I recommend it to others? I would, but I don't have to, all I have to do is loan it to someone and it makes a convert out of them.A+++++
