On the buttons you have to be careful when taking out some of the mobile phones because with me the rocker switch has been lost although the keys are firmly in the frame. Now I do not know if after estimated five take time in and out of the cell phones is there broken something that has ensured that the probe can fall out or whether the just fell out just out of the frame is because the buttons are just plugged in and in through a rubber position held.
No matter what had cases of the two, a call to the seller and the replacement rocker arrived promptly.
Conclusion: Top product and great service on the part of sellers. I can only recommend, even if the price initially seems a little over-priced, which was a good buy.
