This extension is getting more restrictive. Previously, you could have more 450 LOCAL alerts, You could have more than 2 computers sync etc etc. now Restricted to 25! If you are only locking for LOCAL alerts and NOT cloud bookmarks then look else where. Im using my own ram, harddisk and processor. Happy to donate but Restricting Local alerts is just greedy greedy greedy.

very good auto refresher helped me a lot.

This is a mostly superb extension that does exactly what it says it does with precision. Highlighting changes and being able to quickly filter what on a page you're tracking (as well as add granular conditions for the change) are invaluable.

There are a couple of things that could be better about its user interface (why does changing the delay on checking pages make me look at a block of code? why can't I pick colors for tags? why is clicking to view change history look so clunky?), but overall it gets the job done.

Hands down the best auto-refresher and alerter. The SMS push feature alone is gold.

Works as advertised! And easy to use!

A real nice addon for my browser with very good options for what you are exactly looking about an a website! Worked very well!

Seems to work great on FireFox on Linux. Very easy to set up and configure.

Great tool to monitor for changes. I use it on a daily basis and it has helped me alot.

Best extension for monitoring! My recomendation.

Cloud features and SMS alerts plus 10 minute intervals (though shorter would be nice) make this product worthwhile over other website monitor services. Looking forward to a full release app for Android too!

I absolutely love this Add-On!! It works perfectly for my needs, and is intuitive to use. Perfect software, a rarity!!!

Wow, this app is amazing. Cannot believe how well it works! Highly recommended!

Best app for web monitoring

Works phenomenally and is incredibly simple to use!

I've used this for several items and it works great. Always enjoy the continued development as well.

I have tried this as a add on for my browser for awhile and feel satisfied with the functionality

This extension helped me find availability for my COVID-19 vaccine! Well done!

Would not try if i knew its paid 'extension'.
