The best thing about tabterrior is its compatibility with all major browsers, including IE11 which works great for my client's needs (they are mostly in India).
I have not faced any issues while using this tool so far as it has been working perfect since long time now! It might be due some minor glitches here or there but nothing that cannot solved by just restarting your computer/browser - something we do very frequently anyway :) Their support team does help sometimes if needed though they can't always offer immediate solution at times especially during peak hours of business like 12AM-2PM PST when their customer service guys would probably sleep already :P Great product overall!! We use them primarily because our tableaus were taking too much CPU power & RAM compared even after optimising everything possible within those tools themselves! I like that it allows me to do all my work in one place, so when i need help with something specific its there for you! It's not very intuitive at first but once you get used to using this tool everything gets easier! We are solving our problems of performance issues within tableausoftware by creating dashboards which show us where we can improve upon things such as loading time or visual quality etc.
