Thoughts on this PH tester?

I think I'm having a Ph problem with my plants, and since Im starting my first real grow with some Nirvana Chrystal I want things to be as close to perfect as I can get.

The Ph tester I was looking at is this one here.

Would this one work for both soil and water testing?
Does it look like a quality unit?
Thanks!

From the feedback I've read about this product seems to be a good buy .

I bought that PH meter two weeks ago and works great. Was using the ph test indicator (drops) before that, turns out my water ph was way off plants look healthy now.
I pretty sure it's only for water. Don't forget to buy the calibration solutions

Water only. For soil test the run off (first bits of run off)
