I like the feature of the the receiver lighting up the bivvie if theres more then x amount of beeps. I wont buy them, im happy with my little solaces but thats a feature i would be after if i had to replace mine!
With the Tungsten Loaded I don't bother, I just pull it straight, amazing stuff.
With inferior links I'll always do it at the start of a session and will do it again if it's no longer straight for a recast.
