I purchased Luminar 3 (Windows), which has some great features, last year, but it was buggy and at times almost unusable for the first 4 months after the initial release. It's mostly stable now, but can be still quite slow when switching between edited images. I wouldn't buy Luminar 4 at its initial release. The Luminar forums are full of complaints of instability and bugs; wait to see if patches resolve these issues.Dell wireless mouse.WM615.
