    • Excellent customer service!
Easy to use mobile hotspot. It takes less than minute to connect if the signal is strong. Initially, the device could not connect to the network even though the T-Mobile signal was strong. I reached out to customer care and they quickly fixed issue. Then on, hotspot is working fine. I highly recommend the device and customer service. ... show more

    • Works like a charm
Great item and cheaper than all the other options. Also, very portable. I can take it anywhere. I use it to create a wifi hotspot in my car.

    • Perfect for vacation!
Wonderful! I bought this recently for my son to use his tablet on a long drive for vacation. I was surprised at how EASY it was to set up. Initial setup took maybe 5 minutes, and then you just plug it into a USB port. It automatically finds signal (very quickly). You do have to add data like you would with any other similar product, however I only spent $35 total for the whole trip (12 hours there and back and only used in the car) and he was on his tablet quite a bit. I think it is without a doubt worth the money. There is still data left over, and I’m glad I have it for future use. Also, it is very small. I could plug it into and close the console. I did unplug it when he was off of the tablet to save data. ... show more

    • Usb worst
This is one of the worst items I have ever come across on Amazon. It was supposed to be an easy setup, but when I connected it to Wi-Fi, it said there was no internet. I called both numbers that Amazon provided for technical support, and they told me they couldn’t help because they don’t sell items from Amazon. Now, I’m stuck between two major companies, and neither can assist me with this item that I bought from Amazon. This is very frustrating. ... show more

    • Travel Must
This works excellent when traveling in the car. You can plug it directly into a car usb. I was able to do work and my 2 kids streamed on their devices on a 6 hour car ride. The data is easy to buy and monitor.
