5.0 out of 5 stars Just the Job 18 Mar 2013
Verified Purchase
I had an unstable ADSL conndection and in combination with some phone wiring changes used two of these. Speeds have gone from 5.7M to 8.3M and system is now stable. These were certainly part of the solution

5.0 out of 5 stars Replaced old generic filters...much better 26 Jan 2013
Verified Purchase
Wouldn't have believed this could make a difference but it really did increase my broadband speed simply by using this. Also cleared up some phone issues I was having where the broadband would drop out when I made / received a call.

5.0 out of 5 stars ADSL filter By Belkin 30 May 2013
By MrE TOP 100 REVIEWER
Adsl filters are there so you can use a phone on a broadband activated phone-line. They split the line with one phone line output and the other for a broadband cable should you want to plug a router into. This one by Belkin is well made and came well packaged. I like the fact it has a short cable extension meaning I can push my desk closer to the wall. Also be aware that regarding filters cheap ones are cheap for a reason. I bought a cheap unbranded one through eBay once and needless to say the phone line quality was shocking and I realised why when I opened it up and the wires were cheap and the connectors were of poor quality so it pays to invest in and this one by Belkin seems to be just that.

Pros: good quality and well made, useful cable length.

Cons: I fail to see any to be honest.

VERDICT: If you need spares or replacement filters then I can recommend these to you, self explanatory how to use them, be wary of cheap knock offs or copycat products... These are official Belkin ones and they work well

RECOMMENDED!!

5.0 out of 5 stars Solved the disconnection Problem ! 14 Dec 2013
Verified Purchase
I was having problems with the internet connection disconnecting when a phone call was made or received. My son recommended replacement good ADSL filters. These Belkin filters put an end to the annoying disconnection behaviour. Well worth paying extra for good filters.

These were recommended to sort out my internet cutting out problem. As soon as I installed them (which took about 10 seconds!) the problem was solved! I have used Belkin products before with no trouble.

5.0 out of 5 stars Filter Problems 13 Sep 2013
Verified Purchase
I have had broadband now for quite a few years and problems can occur after around three years with filters. you may not notice because you can go on line ring out but you wont receive calls and that was my problem. I had BT filters on originally but they are expensive to replace so browsing through Amazon I came accross the Belkin ADSL in-line Filter, a quarter of the price of the other leading brands. I ordered and it was delivered within three days, fitted within two minutes and is doing it's job perfect. Highly recommended.

4.0 out of 5 stars good product 23 Mar 2013
Verified Purchase
I only gave this four stars as I do not know if they are any better than other filters. I am using them on my computer and phone line and they work but do not improve on the cheap ones I had this may be that there is nothing that can make the line speed faster. they are as advertised an seem well made the wire is part of the filter and and not detached

5.0 out of 5 stars Good quality
Much better build quality than the no-brand filters supplied by ISPs, etc. A pretty good price as well given theat Belkin are usually over-priced.
