Fivepears 35 Pieces Tungsten Carbide Tipped Router Bit Set 1/2 Inch Shank for Woodworking Beginners with Aluminum Alloy Storage Box

made in china?

Can router bits this cheap actually be any good? Can any say how long they have lasted or are all these buyers just casual users?

What surfaces can these bits used on ?

I don't see a Rabbeting bit included, but several reviews seem to suggest they are able to get accurate rabbets. Can someone help me understand?
