Dear Valuable Buyer :
HI,
Before you buy this item ,please read this note .
There is no doubt that this extender can really extand the range .
But there are some problem with it .
The first one ,Many customers reported the hole is too small ,we have make it more bigger now .
The second problem , the extender is attached with Double-sided adhesive ,so it will be easily droped .
I'm really sorry for this .
I have reported this problem to our supplier ,they will solve this problem soon .
When you receive it ,i suggest you to attach the Aluminum sheet again ,so it will be not drop easily.
If you have any problem about this item ,please dont leave a bad feedback before contact us .
I'm willing to solve the problem for you .
Finally ,i want to recommend a more powerful extander to you .
You can search B01BYCPSN6 in amazon .
