YISSVIC Electric Fly Swatter 4000V Bug Zapper Racket Mosquito Fly Killer 1500 mAh 3 Layers Mesh with USB C Cable Stand Base for Indoor Outdoor Black 2 Pack

Genuinely impressed. Nicely made (as these things go), and very efffective. Kills wasps with a satisfying crack and spark first time. Seems to get a good few wasp murders out of a single charge (easily more than 100). Highly effective and entertaining.

Finally we have found an effective wasp exterminator. Instant killing device so not cruel. We are now able to eat outdoors. Great product better than honey jar traps and citronella candles. But keep away from the kids 4k volts. There is a loud energy release on impact. We ordered twin pack. My wife has more kills than me on the leader board.

I am suffering from an invasion (tens every hot day) of what is probably the awkward cluster fly: they certainly are awkward, in that if I open a window to let them out they promptly fly in the other direction.Fly spray only seems to annoy them, and I don't like using a lot of it around either myself or my pets.This electronic swatter does work well, though it does take some learning to use and it isn't as completely humane as I was hoping.(N.B. I know the jury is out on whether or not flies feel pain, but it seems rash to ASSUME that something with such a highly developed sensory system cannot).Firstly, the stand isn't a charging dock: rather the swatter charges from a USB plug. This doesn't seem to matter if using it as a swatter because it still retains the first charge after a good thirty or forty uses. Secondly, it does take a little time to learn to hit the flies squarely and firmly, but it does also seem to be a straightforward matter of practice.I've generally used it in the fixed on position because I find it awkward to hold the press button down, but this doesn't matter much. It isn't what the instructions say but it works. (The instructions are in bad English, which clinched my giving four rather than five stars, but they are decipherable).With something the size of a cluster fly, it can be annoyingly difficult to get a clean kill. If the fly gets caught in the meshes, there will generally been several loud sparks of baby lightning, and the fly will start burning. I've had no problems simply tapping these dead flies out into bin or toilet. The smell of burned fly isn't nice, but I find it difficult to believe that any fly caught like that knows what hit it: it goes in seconds from living to completely dead. It feels brutal, but most genuinely humane methods of killing animals feel like that.More commonly, however, the fly will bounce off and drop to the floor in circular convulsions, from which I have seen them recover. I am not sure what is going on here. I have been able to pick most of these flies up and either squash them firmly in a piece of kitchen paper, or drop them back onto the fly racket for a further, more immediately effective shock. I have occasionally not been able to find a dropped fly, and sometimes the racket has gone off, but the fly has been apparently unharmed or merely slower: it is impossible to guess the injury level in such cases. With so many flies, it is difficult to keep track of the one hit.However, for the most part, I'd still reckon it is probably a lot better than flyspray or traps on the humaneness scale in general, as it is much quicker when it does work, and flyspray has its own share of oblique hits. Traps are generally very slow. And I have gradually become better at hitting them hard, though there is still a lot of room for improvement.I think it probably is a lot more effective for getting rid of this type of fly than spray, though it may depend on a lot of variables, and, as I say, cluster flies seem annoyingly indifferent to the spray I'm used to using.I haven't had a shock from the swatter yet: it seems to be well designed and well guarded. I feel it is necessary to be careful of the fire risk, however. If it can set a fly burning within a few seconds, it might set light to paper etc., in much the same way. The burning flies themselves don't seem to be a fire risk, though I was initially a bit concerned: they char when actually stuck in the racket with a current running, but I've picked them up in my hands straight after without problems. There isn't much volume of fly to really get hot enough to cause anything else to catch fire, and there is not much fuel in a fly and a lot of liquid to damp it out, once the current is removed. However, the water in the toilet does seem the most secure place for a recently charred fly! Also, if you have nervous pets (or children) this may not be the best thing to use around them because of the loud, sudden noise. I can't imagine using it as a passive insect killer because it would not really be passive, between the fireworks and the smell. But perhaps these are less of an issue when using it on things like mosquitoes, which are much smaller. (My current cluster fly invasion consists of flies which are, in general, a little smaller than a greenbottle blowfly).If you're happy with the fact that effective use takes some learning, are not bothered by fireworks, and are not too squeamish about handling/squashing flies when necessary, then I recommend it from every point of view.

Brilliant ! I have been biten to pieces this year!! Driving me insane... so I got the 2 pack of these zapper/ swatters. Well Ive never felt soo demonic than enjoying the frazzle crackle when it fries the blighters! I have got one upstairs and one downstairs. It comes with a C usb cable and I my own a 5v 1A charger plug. I did have to switch it off Automatic in the bedroom as the zapp noise made me jump when nodding off, but atleast it was one less thing to bite me. The dog doesn't like the noise it makes though. So when I feel like im cleansing the house, I leave her in the garden, so it doesn"t bother her.

This is the best fly catcher ever, well worth buying

Bought this as 2 other makes I have 1 broke and the other would not zap if previous bug was still in the mesh. Really sturdy strong racket and work well in stand but the charge cable is to the racket not the stand. Doesn’t last over night in stand if zapping a lot.

As the saying goes " A picture speaks a thousand words ". The picture shows a fly using the Zapper as a jungle gym...in and out , touching every piece of metal ....but absolutely no Zap. When that is the only function of the device I can safely say its not effective. The item shows the battery charge , the light glows but again ....no Zap Zap

Brilliant and does exactly what it says. The wife has become a Jedi when she wields it. It’s quite scary to see this other side of her 😵‍💫. Would definitely recommend buying
