More durable than thought

Since device makes from the beginning a stable impression and this has been confirmed. They meet before the frame a wall or the ceiling until you have a bit of practice, but that keeps the unit from (no direct hit, of course). Battery consumption is significantly and the performance of the high-voltage generator decreases drastically with the battery power. Rechargeable batteries are not recommended. Work really good lithium batteries. They have 1.5V and hold this tension until the end. Even alkaline batteries are after a surprisingly short time empty .... that empty they are not, but they have too little voltage to the device to operate properly.
So far, the device has all the flies reliably stunned or equal done. Wasps are strong but no longer airworthy after contact with the device. The are a few minutes later but again and until then they can pick up good with a glass and carry out. For wasps or larger lithium batteries are very useful. Although the cost real money, but my first set (2 pieces) are not yet consumed and I had to do well with the device.
