what reamp box to get/is it worth keeping this radial proDI?

[s34nsm411]

i had to reamp some guitars for this project im working on so i went down to gc intending on getting a little labs redeye but they said they didnt have any more and would have to order one. that woudl take too much time so i ended up just getting this

which seems to get the job done, but i feel like it might be introducing some sort of hum. this is my first time reamping so i may be doing something wrong.

anyway should i keep it or return it after i get these guitars reamped and buy a better di box for future projects? also what would you guys suggest? i initially wanted to get the red eye because i hear a lot about it but some of the other radials look interesting even though im not sure what the difference is between them

I've got the radial x-amp which I dig a lot. It has a ground lift switch which def helps eliminate hum.
