Wireless GSM SMS WiFi Smart Home House Office Security Burglar Alarm Systems Kit
very expensive on batteries
This alarm is not good, it is very expensive to run, the batteries in sensors are 12V MN21/23 cells that don't last more than 3 months on pretty much standby. I bought this and I regret it.
45pcs 6 15 25mm Mini Wire Brush Pen Brushes Brass Cup Wheel for Dremel Drill
good for the price
just don't set your dremel tool to high rpm.. its a wire brush to clean small items with low rpm
