Those things are great... I've heard loads of good reviews.
And about refractometers in general, it's worth it. Period. Testing and maintaining an extremely stable SG
and in particular reefs is critical. I'd say I use my refractometer every day on average pm and when I'm mixing salt every week is use it a ton.
If you want to save a little money, you could look at a traditional refractometer which is only about $25 and very accurate. However, the Milwaukee will be more effective, accurate, and efficient, plus it'll last a lot longer.
