What do you get?
A battery operated vacuum suction cup with carrying case.
How does it work?
Release the battery compartment, slide out the battery holder, install four AA batteries. Slide the holder back in and you're ready to go.
Push the suction cup against a flat surface, press the green button and you'll hear the vacuum pump start. There's a suction guage that SHOULD start to move when the pump starts. IF it doesn't, the cup is not properly sealed against the surface. Once the guage reaches the green "zone" and maintains it for 3 seconds the pump will automatically turn off. If the tool begins to lose it's suction the pump will turn back on and attempt to restore the vacuum into the green zone.
Once you're done. Simply push the green button a second time to turn off power to the pump. If you hit the vacuum release collar before you do this the pump will kick on and try to restore the vacuum. Not a huge deal, just push the button. But why make the pump work any longer than it has to.
You'll notice that there are multiple filter holes in the suction cup, most of these tools only have one. I'm going to assume one goes to vacuum guage and one goes to a vacuum sensor. Just a guess. In the manual there are rudimentaty instructions on how to change the white vacuum filter. Basically "remove fitler with the tip of a screw driver. Then push the replacement filter into the bottom plate and secure it" One of those "it sounds simple enough until you have to do it" instructions
It somes with a nice cushioned carrying case to ptotect it. But doesn;t come with batteries. I took batteries that worked in my TV remotes, but they must have been close to depleted because the pump sounded like it was laboring. Put four fresh batteries in and it worked like a champ. So if you use this a lot you might want to invest in some rechargeable batteries.. The manual also suggests you remove the batteries when not in use.
It'll grip glass, drywall, tile etc ANYTHING WITH A SMOOTH surface. You might dream about going all Mission Impossible with these and start climbing buidings. Obviously I'm not the first one to think that, since there's a very specific warning in the manual about NOT doing so. (I still think it would be cool) Under IDEAL LAB CONDITIONS it's rated at 440lbs. Under WORKING CONDITIONS it's rated at half that or 220lbs. So I hope you're not too heavy.
The benefit of this tool over others. NO pumping, there a guage to let you know the vacuum is holding and it automatically restores the vacuum should it begin to fail.
The ultimate question: Is it a good value at $150? If you just need it occasionally perhaps a PAIR of another brand for $60 will work for you. If you need this for your livelihood, it might be worth it. I'll leave that up to you to decide.
