(Sorry, problems with the first post of this. Hopefully a moderator can delete that one, I could not)
Thought I'd save someone some trouble.
Bought these based on a Reduser recommendation in another thread. These "Comer" Batteries bounce around in my CORE v-mount plates like a latte in a dirt bike cupholder. Their solution, that I replace my high quality plates with their shittier ones, is troubling. Hopefully they will honor their warranty, I'll update when and if they do. https://www.dandolighting.com/produc...-190wh-battery

Hello, The 190 watt Comer batteries arrived last Tuesday 05-07-19. I did not have a chance to try them till last night. Unfortunately, the V-mounts on these batteries do not fit securely on v-mount receiving plates for either of my cameras. The Comer batteries never lock, and instead slide upwards at the touch of a finger, resulting in catastrophic power interruption to the cameras. I have both IDX and Swit batteries that fit and lock securely on both these cameras. Im sorry but I must return these. Please provide shipping instructions and label.

Respectfully,
Cameron K

Replacement? Are you saying you have batteries that will fit and lock in my v-lock plates, Colin? Because the problem is that neither of these do.

Pity you didn't suggest that on your website on April 25th when I bought these, I would have known not to purchase the batteries. I think we both realize your suggestion is absurd. My battery plates are made by CORE and manufactured to professional tolerances. I received your batteries on May 7th, almost two weeks after ordering. I completed your warranty return request in detail, including pictures of the original boxes with serial numbers on May 20th.
Please refund this purchase and send a return label, as you said you would, on your email of May 18th. I've already been a month without equipment I need because of this.
