I'm regularly using Google translate and it's reasonable. Since a few months Facebook also has this 'see translation' button but they still have a way to go.
About 50% of the time pressing the button results in ... ... nothing after a while. Sometimes the result is intriguing.

For example

"ประกันเครื่องศูนย์เหลือ 4 เดือน"

FB: 4 months of zero warranty left

Google: 4 months left on machine warranty

I guess they'll get better eventually
