Not bad, translations correct and when it doesn't know the translation, unlike google translate, it doesn't try and tell crap. No explanations about the different possible translations. Don't try too much compounds words neither.
Easy to use.
It would be great if you could also see definition of the word as many words have double meaning and direct translation does not reflect it.
Works all time
Great quick reference. Often gives synonym for word. Clear pronounce of words
I think its pretty good it's still need improvement though
