If you count on that it is China, it's quite acceptable. Long (but free) delivery times, with exception of mobile phones and tablets usually not caught by czech customs. I'm missing search by product number (when I want buy something again, selected from several similar items with varying quality and price).
When there is a problem, it gets eventually sorted out, but you have to be patient. It's a good idea to write in simple english because of extensive use of google translate on the Banggood's side.
