I bought two of these batteries to replace my original which was about finished in my RAZR. They work very well. They do not hold power the same as the original, but they are very close (~80%). They are an excellent replacement for my dying original battery and for the cost, I bought two so I would be ready with a spare if needed. They shipped very fast and within a few days I had the problem of having to charge my cell after every call solved. I recommend them for these reasons; price, availability, and quality.
