For anyone who may be interested in a Robocan at a bargain price, Bunnings currently have them for $22ish. This is the whole system, complete with dispenser which has a 3 year warranty on it.
There is both an Indoor variety and an Outdoor one, I purchased the Outdoor one on both occasions.
I paid $60ish ($90 when they first hit the marketplace) for my first one almost 4 years ago and whilst it is still functioning well, I thought this too good an opportunity to miss.
It appears that Raid may have taken Robocan over and hence the need to dispose of the current system and packaging.
The one I purchased today is in the original Robocan box but it does have a sticker on the front of it stating Soon to be Raid AutoMatic Insect Control System
I can personally recommend this system for both home use and camping and the fact that I purchased a second one should bear testimony to this.
The worst day camping still beats the best day working
