Title: Signal bric cell phone booster
Review: I use this for my camper van. Before, I barely could get a cell signal. After installing this booster I have 2-3 bars. Works great and customer service is excellent.

Title: Works great with T-Mobile
Review: Let’s start by saying, I live in the foothills of the Appalachian Mountains, dead spots are a given with any and EVERY carrier here, I switched to Mint Mobile recently which uses T-Mobile towers and at my house reception is less then reliable due to being in a valley and no towers within 4 miles of my location, with this booster the basic effects are where I may or may not have had service without it I now get 4G and where I had 4G I now get 5G (note this is exclusive to T-Mobile due to their multiplexing that runs 4&5G on the same 600 mhz band, Verizon is only ever 4G here), it is extremely rare I am driving without sufficient Internet connection to Livestream a YouTube video in data saver mode, in fact in my testing I’ve only found one spot so far where it buffered for almost a minute due to dropping signal. This thing is very impressive in its ability to maintain a signal. Setup is really simple, but is also where my one complaint is with this and that is the length of the wires, the inside antenna and power cord need to run to pretty much the same location for most people yet the power cord is far shorter which is effecting where I can position things for the final install, I would also like longer wires for larger, like SUV scale installs where the outdoor antenna needs to go at the back of the truck and wires route to the front area for the booster.I’ll also note, most of my testing was done with the phone in a mount about a foot from the inside antenna.

Title: No signal boast
Review: Installed per instructions and saw absolutely no difference in signal strength. Prior to powering up the device I had one bar of LTE but was not able to send or receive emails. With the device powered up I still only had only one bar of LTE and still could not send or receive emails.

Title: Phone booster (for tech savy)
Review: First and foremost, this phone booster will work if setup properly. It will boost a weak signal pretty well and provide a much better signal inside of your home especially if your construction material is fiberglass or metal. Now for the bad which isn’t the company or products fault, so no stars taking away for this one. Phone boosters in general require specific setups to work. I’ve seen alot of different boosters get bad reviews due to improper installations and lack of knowledge with the way they work. So here goes.In order for 99% of boosters to work.1. There must be some kind of signal outside. It won’t produce a signal that’s not there.2. You will need a certain amount of distance between the inside unit and the outside antenna. Typically 40ft is a good minimum. 40ft meaning atleast 40ft high or 40ft out. It can also be split between the 2. I recommend using the entire cable length provided and giving a height atleast high enough to clear most buildings.3. This is for the present with multiple signals 5g, 4g, and 3g. If you have multiple towers near you and your phone can connect to all of these it can and will connect to the strongest signal, which can be a problem if the strongest signal has the slowest speeds. In my case 5g is almost always stronger but depending on location can be the worst to connect too. If you experience this it’s not the boosters problem, it’s a phone problem. Your only fix will be to find a booster that boost the single band/frequency that your on that produces the best speeds and connectivity. For example a 850 band 5 booster will produce boost to that specific band network, in my case is 4g lte and much better than the 5g in my area.4. Most booster antennas are directional meaning you will need to find the best/ closest cell tower and point it at that location. 15 miles can make a different in direction an antenna just a inch to the right or left. It will require some fine tuning with cm adjustments.5.Overall before you leave a bad review please make sure that it is not something else causing the booster to work. I constantly use cell boosters at my work due to location and have had plenty of experience, learning, and cursing at setting them up.This booster works well for it being a multi band booster.

Title: For the tech savvy
Review: I recently had the opportunity to try out the 5 Band Signal Booster and I must say, I am thoroughly impressed. This device has truly transformed my signal reception and has made a noticeable difference in the quality of my calls and internet connection. With that being said it is a pain trying to set this thing up and I almost gave in. There are requirements from providers and other hassles which kind of makes it not really worth going through if you already have decent signal, and there are some long term health concerns while using this over time so I will most likely take this down and just rely on my previous service providers signal. With that being said there are a bunch of Pros that I did notice with it andOne of the standout features of the 5 Band Signal Booster is its ability to amplify signals across five different frequency bands. This ensures that no matter which carrier or network I am using, I can experience improved signal strength. You can certainly rely on this booster to provide a consistently strong and reliable signal.Since using the 5 Band Signal Booster, I did notice a significant reduction in dropped calls and improved call quality. In addition, my internet connection has become much more stable and faster, allowing me to stream videos and browse the web without any interruptions.Overall, I do recommend the 5 Band Signal Booster to anyone who is looking to improve their signal strength and overall connectivity. But be aware of the requirements and hassle you have to go through with this and decide if it’s really worth it or not.

Review: This was easy to install and the directions were clear. I do better with instructions that are clear so I appreciated these.I wasn’t moving particuluarly fast when installing this. From the time I opened the case until it was plugged in and turned on, it took me 30 minutes. Realistically, this is a 15 minute job.It really couldn’t be easier to install. Stick the antenna to the roof, pull the cord through the hatch, attach it to the booster, attach the other antenna with velcro to the driver’s seat, plug that into the booster as well and then plug the booster into a power source. Done!It took me longer because I originally tried to attach this through the back door but I found my “cable management” was much better when I pulled the cord through the top of the rear door instead.I have a real dead zone in my area and I’ve got both an esim and a regular sim. My “Petro Mobility” is through Rogers and the eSim is with Bell. Even though the bars on my device didn’t move for the Rogers sim, I gained a bar on Bell the minute I powered on the device (by turning the key to aux).You can see that I took the photos one minute apart. My phone was not charging in the first photo as the vehicle was off. I turned my vechicle key into the AUX position which turned on the cell booster and voila, one more bar!I feel much more confident now that when I am driving in low signal areas, I’ll still be able to connect to my maps and important apps.I’m really happy with this product! 5/5 stars

Review: My partner works on the road a lot but in the same areas, so she has consistent dead zones where she struggles to have sufficient connection for a proper conversation on her cell phone. It’s very frustrating – I know because I always seem to catch her in one of these spots when I call her. One area she travels in has a military base and that must have some cellular communications systems that interfere, too. Since fitting this booster there is only the one area that still has very patchy service and that is the one by the military base so I think that is down to interference, rather than poor signal. Elsewhere it has improved things to only an occasional, momentary, drop, rather than persistent loss.The installation was easy enough but it could have been made better with longer cables. I realize that the longer the cable, the weaker the signal becomes but I think it could have been lengthened slightly to give more options with installation. Her car is a four foot sedan so I couldn’t run the wire in through the top of a hatchback, it had to be tucked under the rubber around the rear screen and in through the trunk lid. From there it went into the passenger area under the back seat and came to an end just in front of it. I managed to zip tie everything into place but I could have done this in a preferable spot with about 6 to 8 inches more cable. Other than that it was all okay. It works fine with the ‘Lucky’ cell phone service she uses (Bell is the mother company) and she had a work colleague connect her Telus phone to it and she found it improved things for her, too.Overall, happy with the performance of this device but it would be better with a choice of cable length so you could pick function over fit if that proved to be the case. Nevertheless, recommended if you are regularly running the roads through dead zones.
