first i want to tell that the same one apple shop sells is Made in USA. this one i got is from Amazon is made in Taiwan. so thats what you get for £10-15 less may be. this case even its plastic its very heavy and your retina mc book looks bulky and very heavy..other thing they ask to remove frequently and clean the laptop to prevent building dust in between. the top cover which fits to the display is very hard to remove once you put..it almost break the display or the tips of the cover which fix to the display...i dont know perhaps this is a bad copy made in Taiwan and they are selling for cheap..if you want this cover go to an apple shop and feel it and buy a proper one. i paid £30 to protect my beautiful 15inch retina which cost £1800. but it make it bulky and also can damage your screen when you remove..so think about it..for me its a big mistake i bought that at amazon.
Great product, I had a very hard time with the cheap original plastic...the colors on the lcd fantastic and crystal clear..nice packaging. I dont know how they sell it for this cheap. just click it as the original one. only problem is it slightly interfere with the multi function button..if you have big fingers it will be a problem..but in general it is a fantastic product.
