I am 100% sure the fuses with leads are not same quality as the SMD fuses are. I dont have any, and i had a very hard time finding at least one to replace the blown 250mA fuse in my ANENG meter. Richmeter has nothing to do with my ANENG so the $0.39 per fuse from them does not apply to me anyway.
Then i had 1. smd fuse holders and they happened to fit perfectly 2. i had several fuses lying around (from motherboards and routers mostly i think) and i ordered 20+20 for something over 5$ which i am sure it is a very good price for any kind of fuse to go in a multimeter...
Both Aneng and Richmeter are just selling rebranded ZOTEK multimeters. Aneng probably make no multimeters at all. Except for the printing on the front, a ZOTEK ZT101 is a Richmeter RM101 which is a Aneng AN8001. The new Aneng AN8009 is the Richmeter RM111, and the ZOTEK ZT111 and the ZOYI ZT111 and the URXTRAL ZT111.
Definitely, a geniune Richmeter fuse is a genuine Aneng fuse.
About the quality, I do not see it as a big worry. I have been using multimeters for many decades and I am yet to destroy any multimeter by putting a current range across the mains. If I make a mistake and my $20 multimeter does not survive, I will buy another one. The fuse just gives some extra protection. Instead of the 600mA fuse, I just got 1A. It may be too high to protect the multimeter, but it will hopefully break the circuit before the meter bursts into flames.
