Buying advice for wireless mic setup with DSLR

Hi everyone, this is my first post in the lens although I do like reading what people have to say here. My friend and I are shooting a wedding at the end of this May. We have shot several weddings professionally, but they were for a company who had lots of equipment. We are branching out now and doing this one on our own. While we have a good bit of equipment, we lack a good wireless mic set up that we want to use during the ceremony. Do you guys have any recommendations on a good set up which isn't outrageously pricey?

I came across this on Amazon. Any experience or know if it's any good? It's definitely in the right price range

we're going to shoot on a Canon t5i and NEX with the mic set-up going through the t5i

Thanks in advance!
