The transmission speed and coverage range for this application also, but I have not tested precisely because I have so far not had any problems. But I do not think this would drive superior example of a WLAN card of a laptop. So if you want to improve its reception with this product, could be disappointed. For safety reasons there better look elsewhere.
The stick is well made and very compact. Therefore, he also takes very little space, and does not block next door USB ports, like the voluminous WLAN sticks like to do. I really like.
Conclusion: quality and function of this WLAN sticks are very good especially considering the low price. This stick is particularly suitable for Raspberry Pi owners. I would recommend it not only safely, but like to buy for new products once again in order to reposition this not constantly need. When the price goes so readily.
