Recently we decided to do away with our telephone landline and go completely wireless. We had some trouble getting a cellular signal at certain places in the house and this product seemed like it would be a good way to bring better signal to those areas. Unfortunately we quickly found, that though this product does in fact do a fine job of repeating a stronger signal to a weak area, the range of the "Hot Spot" is not even close to what it advertises.We found that even with the antenna pulling in 4 solid bars from outside, unless you were practically sitting on top of the wireless extender you just wouldn't get any improvement. What's more is it seems that there are certain "Blind spots" around the device that don't get any improvement. To give it a fair shot, we experimented with several different transmitter locations and found that the best we could achieve is about a 10x10 sq foot zone with the transmitter in the middle. And of course this location was about the most intrusive (smack in the middle of the kitchen counter). If you put it near a wall or a corner you lose about half of the possible output. We found no reasonably acceptable solution with this product.I have a fairly small split level ranch home (1200 sq feet), and had hoped that I could reliably cover at least the upper level, but in reality, I was only able to get an extended signal in about half of my small 10x18 kitchen. This is not even close to the 10,000 square feet of coverage advertised in the product descriptionIf this product were MUCH cheaper I could accept the performance for what it is, but at $300 plus it is not worth the minor improvement it offers to a limited area. We basically felt as if the limitation in range was tying us to an old corded phone, which is hardly a step forward in wireless technology. Personally I wouldn't pay more than $79 for this product. I returned mine for a refund.
