I really like my Vinmetrica 300. It has come in especially handy in my making of wine from juice buckets. For each test, I made up a summary sheet, similar to what is on their website, of steps. It was a bit expensive but I tired of inaccurate Titrets and test strips. It's great knowing how much free sulfite I actually have. Plus, I had not already invested in a pH meter and I needed to measure that anyway. I did not get the MLF part, nor did I get the burette, stand, or magnetic stirrer. So far it's worked fine; takes a bit of concentration on my part.
