why logo was rejected???

I think it is not very clear what the logo is for.
I see you added that O, ment to be the symbol on the remote control or so.
I think that is Turn ON more than OPEN
Make it more specific, or even add some curves.

Hope it helps

Thank you !!!

I cannot read the idea. I see the heart through the gun breechsight, it looks terrifying. My apologies, sorry.

Thank you for your opinion.
