Could someone tell me how it works? Does it blow the air to the fingers under high pressure? And does it have something inside to squeeze the fingers?

It squeezes the hand-- it tightens all around, fingers and all. The best thing I can compare it to is a blood pressure cuff for the whole hand.It squeezes very firmly- it was a bit too much for me but YMMV.

It essentially has an area which you stick your hands into and it squeezes them. My wife is a pet groomer who's hands hurt her a lot at times since she has done that for over 25 years. She tried it once and didnt get any relief from it. She also hates feeling confined and she said she felt clostrophobic with her hands stuck inside of it. So we sent hers back. Was not happy with product. The premise sounds great, it just didnt deliver.

There is a ballon that squeezes the hand. There are balls that are supposed to massage fingers and the palm is supposed to get warm. No air to fingers. It needs serious redesign. The balls are barely felt. The squeeze is waaay too much and personally it made my thumb joints extremely painful from the squeeze. Definitely not a recommend from me.

This 'machine' has an envelop/bladder that is pumped up with air along with heat. Your hand goes inside and is subject to 5/10/15 minutes of adjustable pressure. It just occurred to me that I'm not using it now. My hands do not hurt the way they once did. Good luck.

Its like a fishing lure clip. Focus the pressure on one side and it will bend in. My wife makes me do it because she has difficulty with it as well. If you use tweezers to squeeze the clip, you can focus the pressure better - just be careful not to bend it.

Hi Mac,It's just a powerful standard hand vac.--no blowing of air so far as I know.

You pump up the pressure and then you can turn it on with one finger love the one I have.

Not at all, it works great. You can do 4 fingers at a time and then both thumbs, still very quick and effective.

Yes, in the sense that there is a pressure sensor on the tip which must be depressed (as in pushed into/onto on the surface being nailed/stapled) before the trigger will allow the air pressure to shoot a nail/staple. The amount of travel in the pressure sensor is approximately 1/4 to 1/2 inches. It is impossible (seemingly) to "shoot" a nail/staple without pressing the tip against a solid object. I guess you could intentionally use a finger to depress the sensor and then have the unit "shoot", but otherwise its pretty foolproof. Obviously not intended for use by children. All of the guns included use the same system.

You need to really squeeze it! Use your thumb & index finger. I initially had the same issue BUT got the hang of it in less than 30 seconds. Don't return it! Works great but the size is small so therefore the distance that it can be seen is limited.When I walk the dog at night I also take a flashlight & wear a safety vest with reflective strips.

It lets air in but not come back out. I used my shop vac to air it up. Works great. About an inch on diameter.

It works like an automatic blood pressure machine, it progressively pumps up all the air cushions for a duration of your choice (from 20 sec to 60 sec), then releases the pressure (during like 5 seconds), then do it again, in loop, until 20 minutes, so you can let it go like that without touching any button for 20 minutes, then the machine stops automatically. According to how you plug the plastic wires blowing air (from the machine to the cushions), it can pump the combination of cushion of your choice (legs, thighs, etc... any kind of combination is possible).

You have to squeeze the holes just right while you are blowing the air in. This keeps the air from coming back out between breaths. You have to pinch the valve so that it opens and the air can go through. Hope this helps!

The dual action pumps will expel air on both 'in' and 'out' strokes.If it does not, it is simply not that type (and shouldn't be advertised as such).

You can do the following: add air, subtract air, check pressure and you can clamp a compressor to them so your fingers don't get tired.

As the others have said, it's a bite valve that has to be squeezed (quite vigorously) at the bottom to inflate or let the air out. I'm sure there's a more difficult valve out there... I just don't know where it is!

Just read booklet that comes with it, no psi is mentioned. it does have a rotating dead weight pressure valve, safety valve and a clamp bar that will bend slightly if by chance too much pressure builds up in it, to let steam escape slowly. it is very safe to operate, i have never had a problem with it in any way.

It doesn't require a lot of pressure, but I probably wouldn't recommend it for anyone with arthritis...even my hand will get sore/tired after awhile. I also agree with Chris's analysis, but I do like it for quick jobs i.e. cat litter, but I have to use a regular vacuum for the whole house. And the mopping feature sucks.

You have to push down. The machine automatically works when and while you're pushing your hand down. You don't have to exert a lot of pressure.

You have to pump it to build up the pressure as needed, but then you just press the trigger for misting effect. It works really well, these saved us while waiting in hot, long amusement lines.
