Yes, this is highly recommended for any non-native English speaker! I'm using it for a two months now and it helps a lot!
Since this is the grammar thread, I will take the liberty of commenting on the quote above, pointing out what might be considered subtleties which the more formal or complex construction brings.
The simpler "I am using" means this is occurring in the present. Since the writer means it has been going on in both the past and continues in the present, it would be more precise to say "I have been using it for two months now...". The fact that it is still going on is implied; if it had stopped, the correct sentence would be "I had been using....".
