3 in 1, moisture, pH and light meter, any good?

Hi guys, new to growing, found THIS on ebay.

Was wondering if anyones used anything similar??? Do they actually work very well or not, seems like a cheap alternative, but thats what worrys me!

Anyone thats tried one of these, it would be great to hear from you

I just got one last night..works ok..I really just wanted it for the ph meter..its accurate

works okay for the price mate

nice one, at least it'll help on my pocket til after christmas when I can hopefully get a digital one!

It's gotta be better than what I have now i guess (nothing lol)!!!
