HLD-4 vs ownuser Pro-E3LvR

[rubeel]

what would you guys recommend, HLD-4 is nice but ownuser has a cable release built into the battery pack.

ownuser info here

any suggestions, i am leaning towards ownuser just cuz of features

My biggest question is whether or not the OwnUser grip is weather sealed like the HLD-4, because if its not, then the HLD-4 wins right off the bat.

Also with the RM-1 remote, the E-3 already has a cable release.

All through it's nice to have such options for the potencial buyer, if you realy interested about weather-sealing go straight to HLD-4 (as did i). Ownuser Pro-E3LvR is not weather sealed but it may have other advantages though...
