CEL-FI GO X G41 | Cell Phone Booster for Home | 4G, 5G, AT&T, Verizon & T-Mobile | Up to 15,000 Sq Ft Coverage | 100 dB Cell Phone Signal Booster | FCC Approved | 3 Antenna Kit

UPDATE - July 22, 2019 - the unit continues to impress with continual boost. If anything, the boost has improved on some days (making me think that environment is impacting the cell signal). Regardless, I continue to be impressed with not only the product, but with Sina and the team at the Repeater Store. BTW, had to add that Sina is not just a sales person - Sina is the CEO!! Imagine that, the CEO of a company that took time on a holiday to ensure that I had the best customer service possible!! Definitely a five star company supporting a five star product. Original Post - Make no mistake, this set up is not cheap at $900!! That said I can say without any hesitation, this sucker WORKS! I have a house in a rural area on a lake. At best, I’d get two bars and 4G. Most times, it was a single bar - and even then, there were days when I would lose signal and have data lag or no data at all on my AT&T iPhone. Couldn’t even hotspot to my iPad. AT&T signal simply sucked due to lack of coverage (inside or outside). I purchased the GO-X because of other positive reviews and after discussing by text the needs I had with a salesman (Ray Martinez). Ray had me check out cell signals using the iPhone Field Test mode while I stood on the roof of my lake house. He recommended the unit I purchased due to poor external signal. I ended up installing on July 4th spending about two hours on the roof installing the pole (included with the kit) and mounting the directional antenna to that pole (instructions were not great, but I like to think I’m fairly mechanically inclined so figured it out). I knew where the nearest cell toward was so pointed the directional antenna in that general direction. I then ran the cable down the side of the roof, down towards the deck and through a first floor window to test. After connecting the antenna to the GO-X unit, then connecting the internal antenna, I fired it up. I had to download the GO-X app and wait for the software to update. Not a biggie. Then the GO-X did its thing and after a few minutes, found the cell towards and started boosting signal. BAM - what a difference!! I went from one to two bars with 4G to a full 4 bars with LTE. More importantly, data speeds were not only reliable, but super quick. I streamed Netflix and Amazon Prime video through my cell phone into my iPad (through hot spotting). No lags, buffering, or hesitation. The APP showed 3 to 4 (out of 5) bars of network strength and a boost of 7 (green) to the internal antenna. I then spent the next 3 to 4 hours making the install permanent, including running the cable from the external antenna to the house along some siding down to the deck and then punching through the siding, plywood sheathing and into the drywall where I ran it to the unit. I mounted the GO-X unit below a window (hidden by some curtains) and hooked the internal antenna with a wire running up the side of the window (again, hidden by a curtain). I mounted the internal panel antenna to the wall above the window where it has the best shot at broadcasting throughout the rest of the house. I did have an issue with the internal cable run as the kit has two 30’ RS400 cables. The first 30’ cable was fine to run from the roof of a two story house, down the side and into the great room. The second was way too long for the run from the GO-X unit to the internal antenna. I pinged customer support to see if they could do a trade-in for a shorter cable. No luck there, but the salesperson graciously gave me a coupon that was good for a 5’ cable. All I had to pay was shipping ($13.44). Sina was great in making sure I had the right size cable and then sending me the coupon for 100% off of the cable - with shipping costs only. I am really happy with this product. Yes, it took me nearly the entire day to install, but is well worthwhile. I am typing this review on my iPad hotspotted to my iPhone that is getting full bars and LTE thanks to this product. Bottom line - it works and the customer service has been awesome. I’m glad I invested the $900 to get the best booster out there.

This product might have been among the most expensive in its category but, it also promised the highest DB game legally attainable. I've been told by several cellular phone / internet providers that living in a trailer in this part of Naples Florida I'm simply not going to get the service I'm accustomed to. After researching and reading the reviews for multiple different products this particular product stood out is being able to provide service inside of a metal building for multiple users. I am a single user utilizing my cell phone hotspot to support my tablet laptop computer and television. Amazingly enough I am able to use all of those simultaneously WITHOUT LAG. Previously there were spots in the Florida trailer home where I couldn't even maintain a good cell phone conversation. At this point not only can I talk on the phone stream videos and work on the internet I can do all of them simultaneously. It is so nice to be able to come in quickly and expeditiously hook it up using the app to dial in for best signal available then be able to sit down and get started on some work or entertainment. Don't misunderstand this product was not cheap but it is worth every penny I spent. I don't like spending money I like it even less when I'm not getting what I paid for in this case I feel like I got a great product at for what it provides was a good price and the service well I haven't really needed it but they've been there to support me through every step of any question I could have had and there's no doubt in my mind that they're there to help other customers do whatever needs done to make their product work correctly. It's a great combination of price quality and service and when I need a similar product in another location I would not hesitate to purchase the same thing again. Even if it is overkill for the next application I would rather spend the money knowing that I'm going to have Superior Service even if it cost me a little more. At the end of the day I shop for Price quality and service this company gets five star on all of the above. The product and the service have been exceptional and I don't say that lightly. Hopefully this helps other buyers who are experiencing similar problems getting internet or even cellular service this is a product well worth considering.
