I knew before hand that unless there is a signal to boost, this amplifier will not do anything to improve reception inside my home. I have a metal roof and the outside antenna is mounted above the metal roof and accurately pointed at the cell tower; therefore, I expected to almost always to have at least one bar but we still drop into SOS mode almost once daily. A lot less frequently than pre-booster but we still drop into SOS mode. That said, reception is much, much better than pre-booster. Best result has been no more dead spots inside the house.

It gave me phone service in the boonies

Easy to install, came with everything to get it working. Nice touch.

Had no service at all in my shop put this in and can now stream tv

The booster was installed, and worked fine for a little over 30 days. Of course, just after the return period was up, the booster stopped working. I sincerely hope that someone in the company sees this review and makes this right. I was hoping to get more life out of the product that a few weeks!

We live in a somewhat rural area and we live along a river, so the area is fairly low. We have pool coverage, so we bought this unit to try to improve our reception. The booster worked but our phones would constantly switch between two different cells and that resulted in dropped calls or difficulty being heard. With no real improvement in our phone service, we reluctantly returned the unit.I gave the unit 4 stars because it worked and I don't believe that the switching problem was caused by the booster. Our iPhones apparently look for the strongest signal and, because we have 2 cells that have about the same strength and their signal strengths vary constantly, the phones constantly hunt for a signal. There is no way that we know of to stop the phone from doing this.

I had an old (6+years) Wilson 460101 amplifier which is only for one room, our living room. It did pretty good for what it was given our outside signal is extremely poor (~-100 dbm) and the house has a metal roof with hardy board (think cement) siding. However, outside that one room, everyplace else in the house sucked for signal.I saw these refurbished 470144 units (multi-room) and given the price savings jumped on them. I got a huge improvement over the old unit even in the living room (12 dbm improvement) and good signal throughout the house (1800 sqft), ranging from -75 to -87 dbm. Now remember, I said our outside reception is extremely poor (~-100) so this is a great improvement and the phones work perfectly now in all areas of the house for voice and data. Are the signal levels perfect? No, and it never will be given our rural location and all the trees but it's a huge improvement. We consider the refurbish unit a very good deal (compare the price to new unit) as it solved our problem.EDIT: One last thing, I notice many people are still using the bars on their phones to determine the signal level. This is wrong. The bars are a 'relative' reading and 4 bars on one phone could be 3 bars on another phone or etc. On Android phones look SETTINGS>ABOUT PHONE>STATUS INFORMATION>SIM CARD STATUS>SIGNAL STRENGTH and there will be a 'dBM and asu' reading. For example, mine currently says -96 dBm 44 asu. These are just two different ways to measure the signal level, probably dBm is a more common method. You should take a measurement outside and then using the same phone measure inside near the WeBoost interior antenna to see your maximum signal increase. You should always see an increase. This amp will give at maximum a 65 dB increase but that also depends on your outside signal level/quality. A great signal is in the -50s dBm, a decent signal is -70s dBm and it goes downhill from there... My signal now is generally in the -90s (in the house) and while this is not a good signal, I can still operate voice and data normally. Note: my signal level deteriorated when the area removed 3G support ~3 months ago; however, it hasn't seemed to affect my phone connection.Negatives: None really but if forced to be overly critical, I think they could explain a bit better for optimum placement of the inside antenna.Recommendations: Place outside antenna as high as possible (height is might!) and ensure you weatherize the connector with coax tape.Note: I used my own outside RG-6 cable (50 feet) since my run exceeded 30 feet and if I used the included cables I would have had to stick two together using the provided adapter, while okay, I didn't want to do that, so I used a high-quality, quad-shielded RG-6 even better than what was provided. I add this tidbit, so folks know they have that option. I will probably get a shorter inside cable in the near future.

It did not appear that the device was able to increase the cell signal by any significant amount. I have 1-1/2 bars of AT&T in a very rural Colorado mountain area and after installing the booster the signal was still not stable enough to have a conversation without dropping the call. Text messaging did not appear to improve and we had to walk around the building to find an area where the service was strong enough to push through. Reminds me of the old Verizon commercial where the caller walks around and says "can you hear me now?". Very pricey product for very little improvement. FYI- It was installed exactly by the book according to directions. I am an electrical engineer and capable of installing this type of product for best results, which we did not achieve.
