We tried to operate it as a test and it performs suction normally. Attention, for suction you press the plunger, you don't pull it as I thought.

I didn't need to use it. I give 4 stars for the careful and complete packaging. Mainly, I wanted to upload the instructions for use

The contents of the package are exemplary. It has everything you need. I tried it on myself without any stinging and it has enough power. Hopefully it won't be needed, but I'm sure it will do its job perfectly.

The product is great and at half the price of the green one. I have tried it on mosquito bites and it really relieves you afterward and the mark goes away. I also tried it on my mother who was bitten by a black insect. After a while, a fluid like pus started coming out of the bite, and while it was painful and relatively swollen before, the next day (after I applied it) she was fine. It takes a bit of force to press it, but that's okay. You immediately feel the suction. The whole skin lifts up. I don't know if it works on snake bites and I hope I never find out. We always have it with us.

I bought it because it was cheap, but I don't think it does what it promises.... However, as a possibility, it might actually be good to have it... it is cheap

The packaging was very well taken care of and meticulous, it was exactly what I wanted and mainly it was exactly what I saw.
I am completely satisfied and it is worth its money 100%.
Order it, it is worth its money!!

It does what it says, it is small and compact, and it also has useful accessories. However, I deduct one star because it is a bit difficult to use, as it requires a lot of force compared to another more "branded" and expensive one that I have (the well-known green one). As a result, most of the time you will probably need help from another person to press the plunger. But it does its job just fine. Even for mosquito bites. If you suck the bite early, you can avoid the itchiness. I recommend it.

Simply fantastic. I got it for my vacation this summer as I also do hiking in various famous mountains in Greece (Olympus, Southern Pindos, Giona). I used it after my nephew got stung by a bee and was crying in pain, and it actually pulled out the stinger as well as the venom that appeared in the suction cup. It has everything you need from alcohol wipes to Hansaplast, and it comes in a wallet-sized package. Essential for farmers, climbers, and hikers.

It is PERFECT because it HAS everything you NEED and it is VERY CHEAP.
1) A strap to prevent the venom from spreading, to tie around your hand or foot.
2) 4 suction cups.
3) A razor.
4) Alcohol pad.
5) And an extractor.
6) (Portability) The box that has all these, fits in your pocket, it's like a big wallet
