    This is just what was needed to bring my connections alive. My office desk needed to be moved to have the hardwood floors refinished while I was working from home. This device connected to an ethernet cable extension and I was able to continue working from another room. Thank you Best Buy for no interruption.

    This is a good connector for extending a cable that is too short - either temporarily or (in this case) permanently.

    Good for only 10BASE-T

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    Got a call for a customer having problems getting abysmal transfer speeds and experiencing file transfer errors etc. Upon troubleshooting I found what is perhaps the worst couplers produced. Actually I found they bought 8 of them off of which went promptly into the trash immediately resolving their issues! You can ignore the CAT 5 or CAT 5e Rating because they are NOT suitable for FastEthernet or GigabitEthernet... The product description is bogus.

    No, I would not recommend this to a friend
