I was running my cable with three splitters and it was really impacting the picture. This little device eliminated all of the splitters and noticeably improved the picture. I've got the cable modem cable going through the amplifier too. Haven't noticed a change there, but it wasn't sluggish to begin with. The amplifier came with clear instructions and was very easy to install.

Was having T3 errors on a cable modem, that is when it looses communication with the host. The modem listed Downstream -19 db with an SNR of 30 db. Upstream the modem was maxed out at 55 db. After installing this amplifier the Downstream numbers read variable +/- 1 db with 34 db SNR. Upstream value was unchanged.
As for the cable picture, it looks as good as a compressed 480i picture can.

After having problems all my life with these AMPS i have hit gold with this one.It has preformed well and cleared up all my problems with snow and picture breakup.It has handled all four TVS,including the two high DEFS.i have.Cable had told me the four way splitter should work and handle all four sets.It's a shame they are the only game in town.I strongly recommend this unit,and at 34.00 it's a steal.Only one problem now is when they see all the five star reviews they will raise the price.Update 9-2-08 bang all of a sudden their out of stock and they don't know when or if they will be back.It working so well i wanted an extra one to have around.

I sort of wish I had gotten one with more ports but this 4 port unit works as advertised and does not inject any noise into the line. I had used a few different 'radio shack' units before where I could detect faint snow or other pattern noise on some channels with the booster. I saw nothing but improved signals with this unit.

I bought this to use on my poor Comcast signal. It does a great job and I can now receive all the digital channels on my computer that I use for recording.
