Went to site to buy a power line extender - the page they took me to was for the TL-WPA4220 - knew that I needed 2 items, (1 to send into the house wiring and 1 to receive at end and become another WiFi). Checked the whole page and nowhere was anything clearly stated that this item was not the whole package - in fact, at bottom of page in the question and answer section, someone asks the exact same question with the answer that item does in fact come as a 2 part package When item came, it was ONLY the WiFi extender! Got onto customer support and they would only offer a returns with refund AFTER item was successfully received back. After showing my disgust at this offer, finally given free shipping offer if I brought the actual 2 part package that was also available I am not an idiot but also, am not 100% tech savvy with everything that is available on the market today, suffice to say - if they believe everyone visiting there site should know exactly what they want before they go online instead of relying on there guidance - then they have in one fell swoop limited there client base and I for one shall not use them again
