GHL 2 Dosing Pump

[Asian Hurricane]

Hi, I have an opportunity to buy a GHL 2 dosing pump for $160. I was wondering if this is worth it? I know there is a 2.1 out now and I can’t learn too much about the 2.0. Is it just an older model or is it completely outdated. I am just looking to dose calcium, mag, and alK. Thanks all.

I am not sure what changed with the 2.1, but I’ve been running the 2.0 for years. Very pleased with it. I can see no reason why it would be obsolete. It remains useful.
