Good regulator
This is a no frills regulator that does everything you need for a basic set up. Bubble counter works great with the needle valve and the solenoid turns unit on when your lights come on. Make sure to use the plastic insert that goes in between tank and regulator, they even give you a spare.

Works good
Im using this for my planted tank and it works fine. The only problem is if the check valve is not working properly the water in the bubble counter will leak out slowly when the solenoid shuts off(may take two weeks or more). I recommend getting one without the bubble counter right next to the solenoid or make sure your check valve is high quality.

It works.
As the title says, it works. It comes as one unit, so no piecing anything together. The bubble counter does not have a built-in check valve as do similar styles, so its a good idea to add one in there somewhere (water backflow to the NV and solenoid would be very bad). The needle valve is difficult to dial in, but can be done and stays there. Regular nylon washers work if you use a lot of force to tighten the reg onto the tank, but a permaseal will not. The specific fitting that this regulator uses is not flat, as other CGA320 fittings are, so 2 nylon washers of specific design are included. Because nylon washers should be replaced every time the CO2 tank is refilled, after two fills youll either have to use a regular nylon washer and crush it down, or contact Milwaukee for their particular washers - they cant be found anywhere else. Overall, a good buy for the money. Definitely a good bet for your first regulator rig.

Complete piece of junk they last about 6 months and are difficult to regulate. Their tech support is condescending.
