2.0 out of 5 stars Poor performance, not worth to buy
Reviewed in Singapore on 12 October 2021
After using about 2 week, there was connection problems. The connection is not smooth every 3-5 min. Really annoying. I can't believe that I paid over 100$ for this. I bought it because it was a well known brand but so disappointed. Just don't buy.
