Can you please clarify:

Is 4.5 ml/min. the slowest it can drip? (ie. .075ml/sec x 60sec/min.)

Geebizz at that price I might just buy another one.

at that price I think I will try one for the 120.

I am interested in this as well.

I have to say the price also scared me.. I didnt want anything cheap going on my tank in case it screwed the whole thing up lol

Are the parts easy to replace? how much would a new head/pump cost?

Well yes and no
yes this is the slowest you can drip per minute but you could set it to drip by the seconds as well.
so the slowest would be 0.075cc/sec X 1sec = 0.075cc
1cc = 1ml

Well I see you might jump aboard.To be honest I was scared at 1st to as I needed a doser for my system about a year ago and didn't want to dish out the high prices.But I love it now and figure I would share the news and give everyone a chance at a decent product.
As most of canreefers know I don't offer any product I don't believe in.
Sorry,yes the parts are very easy to change as I took my unit apart to see what the guts look like.The prices on parts are as its shown on their webpage as I am still trying to get better pricing in them.

Can you send me pricing as well....I need a three head dosing pump to keep things stable....Thanks.

See the first post for pricing

Now this is a good deal.
