I like the specs on it better then I do the accurate 8 more reviews on it aswell was wondering if anyone has experience or have heard about it, not tht I cant afford the A8 I just would rather spend less.

Looking at that model, it looks rather useless. Claimed accuracy is +/- 0.5. I'd want accuracy to .1 pH unit in any meter I bought. Otherwise, you may as well just test runoff.
