I have had it in my possession for a week, but the negatives, as well as the positives, do not need to wait any longer to be seen. The battery in the package was problematic, so I threw it away and replaced it with a new one that I bought. The charging on my new battery is quite fast and it actually lasts around 15 hours as the packaging states. The packaging claims that it works either with 50% or 100% power of the blue light, with the press of a button, but it doesn't even do that. It has a constant scale. I expected it to attract mosquitoes more, but unfortunately it doesn't... If a mosquito goes into the trap, it "throws" it quite forcefully with its current. The flashlight works very well and finally, the charging port cover came off its position quite easily. Overall, it's a shame because it is a beautiful device and I bought it with a lot of optimism, but it proves to be below average.
