I'm currently using the PPM 4 and it works great, I havent had any issues yet. Its pre-programmed to stay between 1300-1500 ppm so you dont have to worry about resetting it in the event it loses power. And it appears to be very accurate. Just make sure to calibrate it according to instructions, which are stupid simple.

Personally I'd go with the 'hydrogen' I have one very similar and it works wonders. It has presets that measure the PPM of the room so it automatically disperses the correct amount of CO2 when it gets too low.
