ShiningLove Optimizer Lite Sight Compound Bow Aluminum Center Aligner with 360 Degree Rotating Head and Body for Archery Hunting

This thing is awesome, had to replace the batteries when I got it but it makes it easier to set your rest center of the bow and string. Way easier than guessing. Shipping takes about a month.

When I received it today I took it out of the package, I pushed the button to turn it on, but it didn't work. So I went to check the batteries, as soon as I shook it to remove them everything fell out. The batteries leak and corroded everything. I waited almost 2 months for THIS S**T.DON'T WAIST YOUR TIME.

Works as intended.
