I use one for ten twelve fifteen and never installed the radial kit.
Seems to me that the radials are more of a decoupling shield than
anything to do with counterpoise, and in my case the feedline is
spiraled around the mast on the way down to choke any stray RF.

The page says the antenna is a .64 wavelength. But isn't the extra
length just compensating for the change in VF due to being inside the
fiberglass tube? Looks to be made well enough for sure.
