The item was shipped in an ordinary plastic bag without any protection and arrived completely broken. I contacted the seller before opening a dispute but he offered 5US then 8US but of course I refused. I was waiting for either money back, or replacement of the broken parts. I finally opened a dispute and Aliexpress gave me full reimbursement. This seller looks pretty d**b, to be honest, because I have been soft with him. 1 star well deserved.
Product ok but got no instructions how to make settings. I have asked the seller for a manual but he don't seems interested in helping me with this.
