You know how websites always publish testimonials that are always positive and use them to help sell the product? Well, after buying the booster (Home/Office kit) from you, I now see why you have all positive. I am an Enterprise Data Center manager for a large telecommunications company. It is imperative that I have the ability to receive facility alarms via text service and then the ability to call in for a status. I manage 8 different facilities throughout the United Sates so you get a feeling for the value of cell signal strength. We own a small get-a-way cabin that we retreat to in a remote area. Rarely do I get any signal and just take it for granted that a 12 mile drive is in order to get two bars on my phone. Like the rest of your testimonials described, about 15 seconds after connecting the antenna and the power, the unit gave me three bars. This product is amazing. With my kit came an extra antenna so I leave one at the cabin and the other in my vehicle. Even though I go to the cabin for a get-a-way, it is comforting to know that I can be reached for an emergency at work or family. To any who share my skepticism, this booster works, and it works very, very well. Our nearest tower in this area is 45 miles out with a repeater at about 15 miles. Trees and other land obstacles block our signal. This booster will bring in a very weak signal and keep it. Thanks JD Teck for the gained comfort. Fantastic product. Oh, BTW - my phone is all digital. My wife has tri-mode and her Analog signal is maxed out when she connects to it.

Please read my comments.. it's a product that works! I am gald to purchase the booster kit and I'm now recommending to all of my friends! I just received my Booster Kit from you and I'm excited to see it for myself if this kit will work for me. By reading from all of responses from your past customers, I was a bit skeptical. The area where I live has moderate signal reception on my cell phone. There are times when I can talk for an hour without any drop calls. Then there are times when I cannot even dial out. The signal strength fluctuates considerably - from no bar to three bars. I don't think this is the problem with my provider. It's because the area where I live is prone to the line of site to the cell tower. In addition, weather also have some impact on the signal strength. My cell phone is a good cell phone and I don't think it has any problem receiving the signal. My cell phone just needs some boost to receive the signal. As I was searching through the web, I found JDTECK and it's products. The web site is simple, plain almost, but they have detail descriptions of their products and how to implement them. I send them an email about my issue and they respond back with a solution. There's no sale pressure or gimmicks. The sale staff is prompt and really knows their customer needs. As soon as I plug in my cell phone to the Booster Kit, the signal strength improved dramatically! My cell phone showed a full signal strength and No, I mean none, zilch, nada.. dropped calls! The improvement is so dramatic, I tested out on all of the dead areas that I know: at home, office, while driving to specific hwy locations, and some rule areas. Yes, this Booster Kits works for me! Thank you JDTECK!

Hi JDTECK, I would like to thank you for your exceptional service. It is extremely rare to find a company that will go to the lengths to satisfy a customer that your company did. The booster performed as well as I had hoped it would. I was able to make and receive calls right from my cabin, which I have never been able to do before. I used to have to drive up to 10 miles to be make a call that wouldn't get dropped. Now I just pick up the phone. The only call I made which was dropped was in the middle of a severe snowstorm with 50 mile per hour winds. I am thoroughly impressed with your product and your service. Thank you

Dear JDTECK Sales, HOLY CRAP!!!! I just got my signal booster kit and this thing is AWESOME!! To tell you the truth i thought this wouldn't work, but when i plugged everything in and turned it on my phone said i had FULL service!!! I live here in the mountains and tring to run a home based business with low cell reception is hard. Now I can call everybody with crystal clear reception from my office. Thank you so much, I am in your debt!!

Dear JDTeck, I just received my new dual band 3 watt booster. I have to tell you that I was very impressed with the ease of use with the hook up of the cables to my phone. The schematic of how the wires are to be used was helpful as well. Upon hooking everything up as described and turning the unit on, I was AMAZED at what I saw immediately. 5 Bars on my GSM network phone from my home. I then took the unit to every room in my house and it was the same thing. I work from my home and have been stuck with my fax line as my main means to communicate. Now with your product I am able to run free with perfect rececption. Of course, I have a bluetooth phone and I can just leave my phone by the booster and I walk around doing business. Thanks again, for allowing me to relieve the headaches of dropped calls and poor reception.

Dear JDTECK, AMAZING and UNBELIEVABLE! That's the best way to describe your 3 watt power booster. My cabin is not only up in the mountains, it is in a canyon tucked up against a hillside. My phone was going from "No Signal" to a weak (no bars) signal that couldn't connect and within seconds of plugging the power booster cable into my phone I got FULL BARS! I called my wife at home (in another town 80 miles away) and she couldn't believe I was calling her from the cabin with a clear land-line quality connection. As soon as I hung up she called me back to see if I could get her call -- and I did -- as clear as could be. I told a few other cabin owners in my area and the word has spread... they all want your power booster now. I told the people at the Verizon store and they said they have a lot of cabin owners who had the same problem I had and will want to get your power booster. Even one of the clerks said his family has a cabin near where mine is and that his parents will want to get one You have a great product! Sincerely

Hello JDTECK, Last week I started working in remote areas where my V60 would give me zero to one bar of analog coverage. When I plugged in the booster it would bump one bar of analog coverage, up to full bars in digital coverage. When it was at zero bars (No Service) the booster would bump it up to full bars in analog mode. I could hear everything crystal clear and the people I spoke with said that it sounded just as clear or clearer then my landline at home. This product exceeded my expectations by far (I was quite skeptical at first). Now I am recommending it to all the people that work in my industry. Thanks for an excellent product. Sincerely

Dear JDTECK, After using the 3-watt booster in my home for a week I just wanted to tell you how pleased I am with it. My cell phone signal went from 0-1 bar to a steady 4 bars (max)! The boasts on your website are not exaggerated in the least. Now I can have phone service while surfing the internet. Thanks for a great product. Sincerely

Tom Burke, Castleton, VT, USA

Dear JDTECK, I received my booster today and appreciate that it came FedX. I was anxious to try it out. I work on the road in Idaho, Utah and Wyoming in lots of mountains and valleys where my cell phone has marginal or no coverage. After I had my booster and antennae professionally installed, I left for Wyoming. Imagine my surprise when along my normal route with "no service", I had 4 bars of coverage!!! In fact there were very few spots where your booster didn't give 3 or 4 bars of coverage all day. I am very impressed with your product and expect you will get quite a few orders from people that will hear about it from me. Thanks again for a great product that performs even better than you claim.
