Trunchen PH meter

I am looking into purchasing another PH meter. I have a tri-meter, and do not always want to move it from tank to tank, and sometimes don't always trust the reading off one meter. So I was looking for some advice on the trunchen PH meter, are they really worth the money?

I use a nutra wand as my main meter for checking nutrients, its pretty handy its good for stirring the tank up too, its not as pinpoint accurate at some meters with many decimal points worth of numbers but they are pretty reliable as long as you keep good batteries in it, as the batteries fade so does its accuracy.

Thanks for the reply NGT, good to know about the inaccuracy due to low batteries. Anyone else out there use this type of meter? I figure that they have to be very common...
