Google translator vs language extension

we are being asked to added Vietnamese language by our customers. Should I use the google translator extension or language extension? Has anyone found 'best' solution for incorporating another language in their store?

thanks in advance

language extension only translates the system text, but not the products, details etc. Google translator translates everything, but not definitely accurately.

thank you. I think we will test our luck with google translator and hopefully they understand its not 100% perfect.

In Language extension . The Product detail info you must written by yourself in dashboard or insert in your database, If not it will leave blank.

But with google translator it will be auto translate it in google.

If you choose Vietnamese language is main langguage, you should use language extension and suggest your customer send you detail of product by Vietnamese. If not, google translator is a best tool
