Short answer - if you’re on the fence regarding this product - go for it. You have nothing to lose, except maybe your pricey monthly internet bill.Long answer - we bought our home “up the holler” in 2009. We moved here permanently in June 2019. We have ZERO cell phone service, unless you hop on an ATV and drive 3/4 mile up a dirt road to the top of a mountain. There, you might be lucky to have 2 bars. If you’re really fortunate, you can check your email and social media while checking over your shoulder for bears, coyotes, or the occasional bobcat. For years prior to our move, we researched internet providers only to discover there are two options for service here and both are satellite internet companies. For simplicity’s sake, we’ll call them Company H and Company V. Both offer maddeningly slow, barely usable internet service at exorbitant prices. We chose Company V. For over $200 a month, we receive “Unlimited Data” which is throttled after 65GB. That is, when we can use it at all. Forget streaming ANYTHING. We kept searching for alternatives. After handing well over $3000 to Company V over the course of 1.5 years, we decided to take a chance with the Cel-Fi GO X, or Sophie, as we now call it (her)? Within minutes of downloading the WAVE app, we got a message from GO-X Expert Ian, offering assistance, if needed. Antenna placement took awhile. Don’t rush it. Our teenager spent a good bit of time on the porch roof until the positioning was correct, but this was facilitated by the WAVE app. We went from Zero bars; I mean not one bit of service to 3-4 CONSISTENT bars of 4G all over our 2 story 2000 sq. ft. farmhouse. Speeds are fast. No more timing out before a page loads. We can now make and receive phone calls on our cell phones. Texting? No problem. Even pictures send quickly. The three of us can be on our phones while streaming a movie with no issue; no buffering. Amazing! We are using the indoor dome antenna, centrally located on the first floor ceiling. We thought the days of streaming tv were over when we moved from civilization to the semi-wilderness. It sounds cliche, but I wish we had found and purchased the Cel-Fi GO X sooner. Yes, it is costly, but it will pay for itself in a few months, once we ditch satellite internet.-If you’re thinking of purchasing this booster, go for it. Totally worth it and if it doesn’t work out for you, you can return it.-Read the instruction booklet first.-Download the WAVE app. It is indispensable for antenna positioning. No second-guessing.-Be patient. The installation takes time.-Contact the Waveform Tech Experts if you need to. We didn’t use them, but it’s reassuring to know they’re on standby, ready to help.High Five 🙌🏼 Cel-Fi GO

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.
