I run two Neptune Dõs and really like them. Expensive, more than they should be probably but I like them

This is the first dosing pump i've ever used so I can't compare it to any others.
These are my opinions (pros/cons) with the GHL Doser 2.
Pros:
1) No more manual dosing. This pro applies to ANY dosing pump.
2) 24v stepper motors for accurate dosing down to .1mL with 4 different speed options. I've found low speed allows approx. 6mL/minute and high speed around 45mL/minute.
3) Allows up to 8 manual doses a day at any time you desire. Automatic dosing up to 150x a day.
4) Has ports for magnetic stirrers. Allows adjustments for how many stirs a day and for how long as well as RPM adjustments.
5) Can communicate and program the unit through USB or wifi/internet.
Cons:
1) Price.
2) Must have a Windows computer for initial setup. Not a problem for most people but I abandoned Windows many moons ago.
The cost was a little bit tough to deal with. After thinking about how much I might lose in livestock due to a failure of an inexpensive chinese unit, which may likely work without any issues, I decided that it was worth the extra money to me. I wanted something with stepper motors for the accuracy which, unfortunately, gets you into the more costly units.

I use GHL Doser 2. I decided to use the GHL doser because it can be used with a smart phone app to set up and run. An it has a very durable motor and pump. You can buy it in 2 ,3 and 4 pump configurations. An you can add pumps to the 2 and 3 models.
I now have 11 GHL dosing pumps. That do Auto water changes and ATO Also additives are added to the tank and in the future amino acids.

If you are any good with electronics, an arduino controlled dosing pump isn't that difficult. I developed mine in a few hours (although perfecting the code took more time) utilizing components purchased mostly from Amazon.
Cool, got a build thread on that?If you are any good with electronics, an arduino controlled dosing pump isn't that difficult. I developed mine in a few hours (although perfecting the code took more time) utilizing components purchased mostly from Amazon.
I haven't started one yet, but it will happen. I just need to find time... 
The Dos is also big and takes up a lot of room.
The cost is about the same DOS two head the only way it comes is 300 dollars
A GHL doser 2 two head unit is 339 dollars. But it does require you to buy an Apex to use it either and you can expand to two more heads.

I have a friend that uses it for his AWO they work fine LiterMeter III cost is still 359 dollars for a two head unit.

Thanks, although costs are not being considered in this search.
So me, its looking like my picks in order
GHL Doser
LiterMeter
DOS Neptune
If you are looking for usability, the DOS is a great dosing system. I have 3 on a 400G reef.

I just checked them out. These seem good as long as your connected to the Apex or another controller.
