I have these silicone protective cover off for three days and I do them well
not again ... possibly for the holder for the car. Whether you really settle it
needs, will show (holder not supplied).
It fits 1a, is unobtrusive, easy to grip and protects the back and edges;
just the way it should be. A restriction on the reception strength I could
not notice (neither there nor in the apt.).
Conclusion: TOTAL RECOMMENDED *****
Edit:
After more than a year of continuous use these shell sits as the first day. NOTHING worn and nothing broken.
