Looking to get a tempered glass screen protector for my 7 plus off Amazon (in the UK). Looking at what's available, there's protectors costing £3 and some costing £10. However, when looking at the features and photos, they all seem exactly the same (quoting same phrases), however reviews are usually better for the more expensive ones (illusions of better quality with higher price?). Seems like it's all rebranding and the same underlying product. Is this correct? Similar thing with clear cases it seems. Lots for very cheap ones with no branding, but more expensive ones with branding that look exactly the same. Should I go with the more expensive stuff, I mean it's only £10 more all together and if it is better, it'll save potentially £100's of damage to my phone. Thanks.
