It’s always good to keep your firestick running clean. Clearing the cache is one way to help keep your buffering at a minimum.
I suggest doing this atleast once every 2 weeks.

The team at Kodi Fire IPTV strongly suggests that you use a VPN at all times.
Be it for browsing, watching Kodi, watching IPTV or anything else – the one that we recommend is Hidden Router. They provide you with very fast speeds, that can reach over 400Mbps, and their VPN service is as low as $6 per month (when paid for 2 years)!
Grab your own Hidden Router and regain your online privacy now!
