The first thing I will say is that this device is not a 100 percent guarantee. Some area just do not have a good signal no matter how much you boost it so be aware of that. That being said, this device worked really well for my friend. It is a bit of a challenge to install though so be aware of that. This is not something you can just put inside your house and expect to work. It takes positioning and installation on your roof to work. Once it is actually installed, it actually works pretty well. It can be a bit of a challenge just finding the right spot for it when putting this device on the roof. It is one of those calibrating the antenna to get a good signal. I try to put everything upstairs as the best results will occur upstairs as signal tends to travel down better than up. That being said I would recommended you install the indoor device upstairs. The device inside does show the signal it picks up and how strong the signal is which is nice. The next thing I would say is if you are not good with drilling this probably will not be as easy for you as there has to be a little drilling to run the cables to each other. The antenna and cable are both meant for outdoor usage so you do not have to worry about any weather damage. There is no wireless connection between the antenna and the indoor device. This device does work best on the roof and the wiring is best drilled into the wall for better management. You do not have to run the wire through the wall per say but it does not look good with the cable clutter. For my friend, I also suggested he place the device inside a bit further away from my router/modem as it reduces that chance of any signal interference from the internet modem or router. The cable length is pretty long so you do not have to worry about not having enough cable length to reach the antenna above the house. The digital indicators are good in displaying the needed information. Be aware that this booster does run a bit warm so make sure it has properly cooled room and not left in direct sunlight. It does come with majority of the things you may need to install it. The antenna is literally like a satellite dish where you would need to move the device around to get the best signal. You want to move the antenna around and I would recommend doing this with another person for safety. This process can take several hours depending on if you need to adjust the antenna accordingly. The main box is very simple but big so finding a spot for this can be a bit annoying. The wires are shielded so they will be okay outside but not the actual device. It does boost the signal significantly in my opinion and it does exactly what it is suppose to. My friends home has significantly better signal all around. There are no longer any dead zone in his home. The signal in my opinion is significantly better better than what it used to be. One thing I will note is that this device is not a guarantee of a signal boost as again some places are just impossible to get a good signal.

I will tell you that this product works for me. But, if you are not-so-technical, it isn't entirely obvious that it does work until you do a bit of testing. Let me walk you some advice for this product.1) Take the "cellular amplifier must be 20 feet away from the wired antenna" advice seriously. If it is that close, you can turn your site into a "no-cell zone". The further away the two are, the better.2) There are good free products out there to help with the testing. Test your network throughput before and after installation. Know where your cellular towers are at. Use the app that comes with the product when you're pointing your antenna. I recommend using speedof.me as a bandwidth testing site. I got my best results testing with that site. To find your cellular towers, use the Opensignal app (I use it on my Android phone). That app will show you where you are in relation to your cellular towers. That helps in pointing your antenna. Don't be afraid to do some driving to get a feel for what the tower provides (I had one tower provide 5G, the other tower didn't).3) Use what you have at home. I use a Genie receiver for Direct TV. That has a bandwidth test that - while it isn't detailed in any way - it does provide a "real world" feel for any improvement.So, some details about my situation....I'm on the edge of farm country in Central Ohio. I just moved my cellular business to T-Mobile (because I could get unlimited bandwidth on their system at one price). I have a OnePlus 9 and the most current T-Mobile hot spot for internet.For the OnePlus, where I would get one-bar in my house (Aluminum siding), I now get 4 bars. Where I wouldn't get 5G before, I'm on the fringe of getting 5G at times at the same location in my house. However, I would not necessarily get improved data bandwidth on the phone.My bandwidth did jump for the hot spot. I went from testing at 15-20Mbps before to 90-95Mbps after. My hotspot tells me I have poor reception...but the bandwidth tells me differently. Make sure you do your testing.The DirectTV test told me that where I would be okay for HD streaming, I am now good for 4K streaming with the system.There is probably some discussion and research about cellular bands I should do to provide some reasoning behind all of this...but I want to keep this simple.The product itself is good. If you're like me, you will need an additional mount for the antenna beyond what is provided with the product. I used a wall mount that you could mount a satellite dish to your house with.The seller went out of his way to send messages to me about providing assistance. I didn't take him up on that...but don't let that stop you if you need help.I don't know what working with the manufacturer is like.So here's the bottom line. Do your research and make sure the amplifier will work with your carrier. Make sure your situation will provide you with the ability to separate the antenna and sending unit by at least 20'. Do your testing before and after installation. If you are like me, you will be pleased with this product.'
