I’d give a ZERO

I ordered my horn and received no updates from horn kings. After roughly 3 weeks I emailed and called/left messages and still was not contacted by them. Finally I got an automated update saying it shipped. Package arrived damaged and the horn was broke. Took pictures and emailed it to horn kings over a week ago and still haven’t heard from them. Their customer service sucks!!!! I’ll never do business with this ****** company again.

Do not buy

Couldn’t use because I never received the compressor. Have made multiple phone calls and sent multiple emails and have not got a response or answered phone call. Do not recommend buying anything from here
