Wireless windlass remote for under $10

I wanted to be able to raise and lower the anchor from the helm. the remote available from the manufacturer is over $350 with the control box, but you can get a 2 channel remote and control box from AliExpress for under $10 ( I paid 13 because I wanted a second remote) and it works great! Here's the link to the remote and receiver I used: https://a.aliexpress.com/_mq0Ga4k
