Very bad product, the seed is not very good, it starts to get heated after a little time of use and battery drains quickly, the quality of the product is also not good, for the money we pay it is not worth it, the Hotspot connectivity is very slow, I have used it for 6 months and the battery started to bulge. It does not feel like 4G network instead the seed feels like 2G or maybe 3G, I will not recommend it to anyone, instead of paying money for this and get seed of 3G signal, use your mobile Hotspot to get internet connection for your laptop.
Thank you
