This product is exactly what he announces: increase the range of a wireless network: Several dozen meters (in open area) with its original antenna and even if connected to a larger gain antenna. The supposed button automatically synchronize with my network did not work on my own but it was very easy to do with the utility provided on CD (5 minutes flat). In short this price, this is a risk free purchase and good life easier (no need to pull the ethernet cable as it should, for example, a router)
I take this comment after two years of operation (continuous, it was never off) to confirm that it still works perfectly as he sometimes finds himself exposed to high ambient heat (in a local south on Hill Azure). It's really a reliable product!
