Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

Pros:
-Very Cheap
-Easy to use
-Easy to install
-Works Fine !
Cons:
I bought one to install in my variable source, but I didn't read that it works from 7.5V. So, when I needed to use it On 3V coudn't read. Then, I did the adaptation in the 7805 using an small 9V batery and then it worked very well. Now I can use it on my variable source from 1.25V to 15V without problems.
Other:
Now I will buy more LCD's and I will try to use on another variable source from 1.2V to 30V.
Bottomline:
Thanks for the manufacturer.
