mCover Hard Shell Case for 15.6" Acer Aspire 5 A515-43 Series (with AMD CPU) Windows Laptop – A515-AMD Aqua

Will it make opening lid easier?

Does it fit the a515-46-r3ub?

I've been looking everywhere, but is this case compatible with the acer aspire a315-54 model? i can't find any.

Does this for my laptop: acer aspire 5 slim laptop, 15.6 inches full hd ips display, amd ryzen 3 3200u, vega 3 graphics, 4gb ddr4, 128gb ssd, backlit
