Summary

The Good

It is fairly user-friendly and the cost wasn't too high.

The Bad

It picks up tremendous amounts of noise, and the pH jumps around a lot.

The Bottom Line

It isn't super accurate and it picks up random adjustments even though you haven't added anything in. Overall, if you don't require extremely sensitive numbers, then it'll be good.
