    5.0 out of 5 stars Shazam! zBoost SOHO Extreme is a superhero for fringe coverage!
    Reviewed in the United States on May 12, 2013
    Verified Purchase
    I live in the country in a fringe area and could not make calls and barely text from within my house. I knew that if I went on the roof of our two story home that i could get better reception. I could talk outside at ground level but still the signal bounced from tower to tower trying to get a clear connection and would drop calls. I hesitated to order this due to the mixed reviews but for the price (I purchased a returned product from amazon at a discount) I couldn't pass up a try versus the better reviewed Wilson products.

    Prior to hooking the system up I had a signal of -105 to -115 dBm in my home - that's a dead zone (occasionally I would get -98 dBm). I hooked the outside antenna up right on top of my tv antenna and routed the cable via the same route as out tv connections. Then I hooked up the amp and inside antenna and placed it in my kitchen facing the mass of my interior. We live in a 1930s cape code with plaster walls and the kitchen is an outer wall so I expecting to get reception in the kitchen and adjoining living room only which is all open space.

    I turned it on and checked the signal - my phone read -78 dBm in the living room and if I went in the kitchen and held the phone about 3-4 feet from the transmitting antenna it dropped to -60 dBm!! I can't even get that signal on my phone unless I am standing next to a tower around here. Even better is that the signal reached upstairs to improve my son's phone reception too and our 3g modem. It has also penetrated the plaster to reached to the ground floor bedroom and bath to give enough signal ( in the -90s) for keeping a call! So even in the farthest areas I can now talk which I previously had to go outside to do!!

    Additionally, I have a program on my phone that tells me what tower I am connected to and before the install it constantly jumped towers. Now I am locked on to a single tower which means no dropped calls and a steady internet :) Couldn't be happier!!

    Went from 0-1 bars before installation to 4-5 bars. Reception is so good I dropped my land line carrier. Saves money in the long run for me, works the best in the room its installed in. Doesn't broadcast through walls well but I use it for my home office no more dropped calls for me.

    1.0 out of 5 stars Didn't get what I needed....
    Reviewed in the United States on June 17, 2014
    Verified Purchase
    I must admit that most of this is my fault up front, but still very frustrating. I am not a techie and so I thought I had researched well before purchasing, but nope. Once I received my order, I found that the installation criteria would be tough to meet and then I read that this particular model only works if you have at least 3 or more bars outside and we do not, but the company does make one for those that have 1 bar, which is what I need. So product did not work even after I tried because I didn't find any of this out till after I went to trouble shooting on manufacture's website! Also the installation requirement is that the antennae outside must be 15' vertically above the panel in the home. for us, we have only about 5-10', so we attempted to install on a pole, but it can not be metal, so we tried PVC, but found the problem was the reception or bars. None of this would be a problem if I could return, but since my husband works shift causing us to wait 4 days to attempt installation only then to have a bout of rainy weather lasting a week or more and then we had holidays and life events that we were committed too and so we missed the return or exchange deadline for amazon. So here I sit with a costly product that I can not use.... All that to say if you are going to buy by internet, research products at manufacture's websites and not just amazon.

    3.0 out of 5 stars Still no change, but will keep trying.
    Reviewed in the United States on December 26, 2014
    Verified Purchase
    I installed the system, everything per instructions, the antenna is 17" elevated above where it is installed in the house from the outdoor antenna, I read the further away the better so I wrapped it for a full 140' CAT6 from base to antenna to the top of my 2nd story home and don't see a single bar difference whether I turn it on or turn it off despite standing right next to the indoor antenna.

    To be fair, after further research of other feedback everyone says this unit provides no more bars than the best you can get off the top of your house but, despite I get 2 bars out doors, the fact I bought the unit good for around 10,000sqf to cover my 2,000sqf home supposidely good for homes with almost no reception, I was disappointed but others say I need to try multiple locations around my rough line so I'll continue this week to see if I can find a better spot. The dissapointing part is this is supposed to amplify poor out door signals and I over bought to get the best.

    End result for now (I'll update if things change) without it on, I get 1-2 bars. With it on and 5' feet from the indoor unit, my cell phone fluctuates between 0-2 bars back and forth / on and off. No difference seen as of now but I'll give it 3 stars to be fair till I atleast try some other alternatives. I also read to trash the CAT6 cable it came with because it's too thinly insulated and get a thicker insulated CAT6 so I'll be trying that hoping that works but more money, more money, more money. The kit should work out of the box so the proper cable should be provided if it's truly not suffiecient.

    Nothing more to add for now but will update when I try a few other options.
