It works great. I recommend.

Helps a lot, good recommendations!

Super fijn app. Nederlands en Engels controle ik merk dat mijn taalvaardigheden er op zijn veruit gegaan. Jammer dat je voor extra functies moet betalen daarom geen 5 (wel begrijpbaar maar daarom geen 5 sterren)

Very happy to find a spell checker that works on multiple languages.

While it is working in normal circumstances, this addon breaks eBay! When listing new item for sale, eBay form is blocked from working, and typed formatted text does not translate to HTML and item description remains empty. This breaks even existing eBay listings, when you click to edit a listing, click text field, description is completely gone, submitting listing with changes will cause entire text gone! Please be careful when working with big text fields, this addon is not compatible with everything!

Typed a few sentences, it corrected a few errors, then told me I needed to pay for premium to detect any further errors.

Premium might be worth it for some people, but for me it's not that serious. I can live with the occasional grammar mistake.
