I bought a skin for my Spark.  



The goal of adding a skin is:
- Making the Spark more scratch proof.
- Make it more visible in the air. Notice the skin I bought is red.
- Add a personalization touch to it.

However, I see some cons:
- More weight.
- More

Do you use a skin? Have you noticed any difference?

Great skin. It seems like you really into red color. There are a lot of users like using skin and it may cost you some time and patience. Please be careful when you deal with the handwork.
