When identity theft is on the increase this is perfect for disguising personal details. I won't stop shredding also but this ticks the box for the covering the ones that don't make it to the shredder! .....and if you have young children they love stamping :)
If you are a little tech minded (and brave) this was an easy replacement and now my phone works perfectly. Invest in a proper set of tools (£8) which are always good to have before tackling any thing like this, it will make the job easier and minimise visible 'tampering'.
