Cheap and effective unit.
This is a basic voltage booster, stepping up from 3.7 volts to around 30,000 - 50,000 volts. It is highly unlikely that the unit produces the 1 million volts often claimed with these devices.
If output terminals of device are maintained wider than about 12 - 15mm the extremely high capacitive voltage buildup within the unit will destroy it very quickly. The warning on the website regarding this point should definitely be noted.

The SJ35-04PC Davey pump is good product at a good price.
1 of 1 found this helpful The SJ35-04PC Davey pump is apparently well made and easy to fit into water line to replace second faulty Zenox (Italian made) pump. This Davey pump is made in China, which probably explains the very competitive price of the unit via eBay out of Melbourne.

Worth the money at $32.
A smoke alarm that is competitively priced and appears to be well designed and made. It needs to be permanently wired into a 240 volt (light) circuit by a qualified electrician. Backup battery is not long-life and needs replacement about once a year. Easy installation and well positioned 'Test' and 'Hush' buttons. Although the claim is that there is stainless insect mesh around the sensor, the ability to quieten the device is important at 3 am in the morning should a tiny spider gain access.
