    I thought I might be having a conflict with my smart tstat and CUJO, but this was not the case. I opened a support ticked and received an almost immediate response. It was determined the problem is within the stat. Case Solved.

      Hi,
      I'm glad you had your issues resolved really quickly. Some IoT device manufacturers disregard network safety, but thankfully, there is CUJO for that!.

    CUJO destroyed my router!

    This product is a disaster! It worked very well for a little over a week and then I started to have connectivity issues with my wireless devices. It ruined my Linksys EA9500 router. I am having to get it replaced, not something I should have to be doing and I loved that router! I can't believe they released this product on the market before it was actually ready to launch, my router paid the price! Thanks CUJO! Retuning to Best Buy tomorrow! Done! Do not get. CUJO probably isn't even necessary and if you really need another layer of security get something else.

    This is a great product, and easy to use app. The app also informs you of blocked threats.

    Can't see the value

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

    It frequently blocked activity from my devices, then said I should check for malware. But nothing was ever found. So what am I supposed to do with that? Plus, a frequent intrusive adware that was popping up on my phone was NOT blocked. Returned it to the store.

      Hi,
      First and foremost, I am very sorry for all the inconveniences you had. It seems to me that there might have been an issue with the CUJO setup. If you would give CUJO another chance, I could make sure that our most senior 2nd level technician would handle your case to ensure that there would be no problems whatsoever. Once again, I am sorry for the bad experience and hopefully, we will see you again.

    Don't Buy it, if you have 940Mbps/860Mbps

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

    I Purchased the CUJO when I had a 150/150 Mbps network via FIOS and it worked fine. When FIOS offered me 940/860 Mbps network speeds, CUJO slow down my network speed to 500 Mbps. I had to return it. Don't buy this if you have upgraded to 940/860 Mbps .

      Hi,
      I'm sorry CUJO didn't work out for you. Internet speeds do vary depending on individual networks. Since CUJO does have 1 Gbit ethernet ports, the only bottleneck possible is from the software side. We are constantly improving network stability for all kind of setups, but it is a daunting task. Hopefully, you will be able to give us a second chance later on, once we have optimized CUJO to better suit your network. Thank you for the review and hopefully, this is just a small setback between you and CUJO protecting your network.

    Does not function as advertised

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

    The application would not allow me to do the simplest functions such as blocking specific websites in a profile. The only solution that technician could offer was for me to use a different Android device other than a Samsung Note 8 to configure the software or un-install the cujo from my network. I now have a $250 boat anchor that could not do the most basic security functions. This is NOT a product that I recommend.
