I have been looking and found thishttp://cgi.ebay.com/Waterproof-pH-m...emQQptZLH_DefaultDomain_0?hash=item4ced709f5a I was wondering is this too good to be true? Its waterproof has 2 year warranty and comes with batteries and solution but it seems cheap compared to the 1s I have seen people use like the 60 to 80 dollar 1s. Is auto calibration good? Or is it better to self calibrate? I am wanting to know what you folks think?
