Please stay away from this company as they are not serious and they do not care about the satisfaction of customers. They promised to send me a track belt mechanism within days and finally and after sending them tons of emails they sent it after more than a month... I agreed with them to send it door to door but what happened is that they shipped it to the airport. Currently, the worst thing is that I cannot clear the customs as they did not provide a certified invoice and they do not respond to my emails. Avoid dealing with this company. They work under the umbrella of Alibaba
