On the resell value I agree. The value is more like £10.
Yeah, I would not pay more than a tenner if I needed one.
But the argument that it is worn out for dealing with voltage transients really does not hold water for me. For the most part, it either works or it doesn't. The value of £10 reflects the likelihood that it will stop working sooner rather than later, not that it does the job better or worse.
Agree 100%, sure caps can go bad and may be a issue, but these things can keep working for years.
I had a Netgear router with ADSL modem many years ago, I gave it away when I went onto Wireless broadband about 12 years ago, and it is still in use and working fine.
The ECI DSL modem I had went pop, but I am pretty sure that something happened on the line to do that as my phone went off at the same time. That is why I borrowed my neighbour's Huawei modem and then eventually got my own.
The Huawie one was still working fine until I changed to FTTP mid last year.,
