Item arrived as prompted, in a big cardboard box, possibly the size of a router box. I take it Amazon couldnt find a smaller box to put these into.Build quality could be better as they look flimsy, but one thing is that they are quite long.Installed these on to the Tomato flashed Asus N66U router, which had been previously using the factory supplied antennas. As the router is installed in the loft, as we are surrounded by a crowded 2.4ghz spectrum and the higher the unit can be placed the better. Signal strength went from 1/2 bar to 4/5 bars, on both 2.4 and 5 Ghz. However that isnt the end of it, as there is a park 200 ish meters away, between our house and the park, there is a 2nd row of houses, amongst a pub, schools, a library and a health centre. Whilst at the park, i thought id give it a go, a quick scan on the HTC smartphone, i managed to pick up the 2.4G signal from the Asus router, it was between 1 and 2 bars, signal strength between -70 to -85db, previously the Asus didnt go this far in terms of coverage, so have free wifi in the park now. No one uses channel 12 or 13 around here, so it should be all good, better hide the SSID and add some MAC rulesUsing the Items are well recommended, if you can get your head around a big shipping box and the build quality.

Not any better than my original antenna.

Quick delivery and good quality. It doesnt look like it has improved anything when you look at the signal on devices but devices are now working in areas of the house that had issues so a good improvement.

Purchased these to extend my wireless range to cover a dead spot and avoid another AP. However these did absolutely nothing when compared to the 3dBi original antennas, infact transmission speeds were somehow slower. The build quality is awful and they are flimsy. Thankfully I was able to return them to amazon for a refund.I have now purchased Draytek antennas - firstly they are much better build quality, secondly they expanded the range and I get fantastic transmission speeds (Essential when the internet connection is 200mbps), however still needed another AP to completely cover the dead spot.In conclusion - these are awful - do not buy them. You are better off buying an AP than upgrading antennas.

Easy to fit, and extended the range of my TP-Link Archer C8 (V1) by a small but useful amount - meant I could dispense with previous essential range extender to get good coverage within house.

Good i think 1 broken buth it were because it didnt click then with little force it were perfect again :)

I had really high hopes, but to say the least, I'm disappointed with this product. In my case, these did not have any noticeable improvement on either the 2.4 or 5 GHz network coverage. They are very long and it was awkward to position and find enough room for them with the router under the desk. I tried fiddling with their direction, but they wouldn't stay in a 45 degree angle, taking even much more space. I tried different wifi channels, but in the end, it was not possible to get any improvement from the router's own antennae.For this price, I looked for big improvement, but sadly this was not the case. Not recommended.

Great antennas that improve reception. My only slight complaint is that the delivery time was very long (2 weeks)
