I bought this dell MS111 optical mouse 6 months ago and it worked really brilliantly for 5 months and in april it stoped working means its right side click/button stopped working and after somewhat 1 week its left click/button is also not working properly.
Previously also I had used dell's mouse which gave me a service of almost one and a half year and comparing to that this product of dell that mouse was very much better inspite of a much older product than MS111.
I also want to tell that before this dell ms111 I was using a mouse of enter and that gave me the same service as the mouse of dell which I used before enter and comparing dell and enter , dell is a very much bigger brand and getting this service from dell this time was not expected .
But I believe that next time when I will buy dell's mouse it will give a good service because I still believe in dell.
