Verified Purchase(What is this?)
This review is from: ADSL Microfilter (Electronics)
Very cheap which is a good point in this case. Lets not forget that this is very simple piece of equipment, some wires inside and a plastic shell. Did the job. However, I didn't experienced any improvement in the quality of the Internet speed as others did. For the sake of facts I had run some tests just changing this device with a similar one and there was absolute no difference in Internet speed. This device is an intermediate connection between the wall socket and the modem.
