VerifiedMissing Order & Unanswered Email
I placed my order in March, and as of today, May 4, 2025, I still have not received it. The package does not even appear to have left Germany yet. I have contacted the company multiple times but have only received a single response. Meanwhile, the company continues to send requests for me to review the items that have supposedly been shipped and when I give a bad review they ask me to email them! This demonstrates a high level of disorganization within the company.

This item was never delivered either! I've been waiting for it for three weeks too (order from June 27, 2025). By the way, it was also paid for three weeks ago (July 1, 2025)! ! The store has been unreachable by phone for weeks. I haven't received a reply to my numerous emails. I'm absolutely furious!!!

VerifiedSo Far So Good!
We just installed it and so far so good. I have been able to sit outside without any bites (I am a magnet for all things blood thirsty). Have not connected the CO2 yet so hopefully this will last the whole of summer!

VerifiedAfter a month of use
I bought the set with the CO2 bottle and the 10h22-hour timer. Given that the device keeps running after 22 hours, if I had to give my opinion, they could make a little effort to improve the slightly noisy motor—I do mean slightly. Mine is on a terrace, so it’s not at the back of a garden. It’s a shame you can’t add a short video or photos.

VerifiedREDUCE YOUR CO2 COSTS AND SAVE MONEY WITH THE BG-CO2 TIMER
Depending on the mosquitoes you are bothered by, the mosquito species are active at different times of the day and night. Thus, with our BG-CO2 Timer, you have the possibility to limit the CO2 output to the main activity times of your local mosquito situation. Therefore, the CO2 gas bottle will last longer and you will save money.
