Lobby crafting question

[WolfCyr]

Hi, does the bonus of a given item stacks ?
For exemple, the fences. Does I got the bonus of the one that is selected or the bonus of all the ones I had bought?
Second question, the fences are improving the gadget efficienty, but it gives no more details. It improves respawn time, duration ... ? We don't see the bonus in the item stats.

Thanks !

First question answer: You only get the bonus of the selected item.
Second question answer: The efficiency is equal to the damage. The higher the efficiency, the easier it is to kill someone. So an increase in efficiency means that your gadget will do more damage.
