    • 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

    • Works great! Easy to setup and use.
Works as expected. Great for use as a car hotspot. Connection is easy to set up and provides good speed relative to the cost of the device. I'd recommend!

    • No setup instructions
I was not able to use this device. No instructions are provided for setup. No onlinr links to instructions are provided. Passwords and keys provided on the device stickers did not allow access to wifi access point. Strongly do not recommend. Will return.

    • Worth the money
I purchased this product to use with my DMR hotspot while on the go. The initial setup was a bit tricky, but with the help of customer support was able to get it running. It seems to be doing what it says however when switching between networks there's a little bit of a lag. But this is better than losing a network altogether. Overall I am pleased with the product so far. I am on the Verizon network on my cell phone and have taken this thing to places where I know I don't get Verizon coverage and was able to keep my Hotspot connected to the internet. I would recommend this to anyone who is looking to use a DMR hotspot while on the go ... show more

    • Works great just as advertised.
Signal strength has been great. Speed is on par with 4gLTE. When I first activated the SIM it took about 15 mins before the activation took. After that all was good.
