Absolutely awful! Really poorly made products, iPhone 7plus case lasted no longer than 2months before falling apart, dust and dirt has collected in the case and scratched the aluminium body of my iPhone, the case is knackered now and I have emailed tech 21 2 weeks ago for a replacement as it is under warranty but I have had no reply! DONT BUY TECH21 it s rubbish!
