I just downloaded this so I had an easy reference. Had no issues with the download. Fast, easy, and works great! Can't tell you how many times I was unaware of how high gas fees were and cost me way more than necessary. Will be using this tool moving forward. Not to mention the price monitor option is 100% more useful than me having to bring up TradingView or go through MFA to access my apps and check the price.. I can now access in one click.
