I use Verizon 4G LTE and I read a lot of reviews for this product before buying.  A lot of reviews said that it worked with their Verizon 4G LTE and that this product no longer gets hot which is why I bought this.  It gets extremely hot, and my signal doesn't get better or worse when I use this product.  I had to remove the brackets completely since I suppose they were designed to hold small flip phones or something, because there is no way my Samsung Galaxy could fit in this thing. I wanted to return this product but they wanted to charge me a 20% restocking fee so I figured I would make sure I am using it correctly.  I wanted to give them a chance since I travel for worked and used it in a lot of different places and my signal never got worse or better when using this product.  The signal strength on my phone remained exactly the same.  This device also kills your vehicle's battery very quickly since I suppose it uses a lot of wattage which is why it gets so hot.  I suppose it works for different networks even though they claim it works for all of them.  If you asked me I would say that this company is a scam, and I am not that type of person to throw around false labels.  Especially since they renamed this product and charge a restocking fee, they probably are aware it doesn't work and will pack up and leave once the word gets out that this product doesn't work.
