We switched this year to the King Innovation DBSR for everything except our decoder systems where we use the 3M™ Direct Bury Splice Kit DBR/Y-6.
The DBSR locks down the wires so they are completely secure. We even use the small units to wire the solenoids. Not one issue since we started, very uniform for our company and I absolutely 1000% hate anything with WHITE grease / silicon in them! LOL The blues are absolute junk IMO, sorry but I have seen so many failures over time.
Find the best connector you can install at a reasonable price and stick with it.
