I like how easy it was to set up, our entire team has been able use this product without any issues! The support from K2 staff are incredible as well - they always get back in touch quickly if there's anything that needs fixing or clarification regarding their products/services- even when we're not paying for them!! Nothing at present but would be great improvements:- 1) more options available within each page (ease navigation).
2.) Ability add custom fields into pages.- 3rd party apps integration could also improve? We have used several different content management systems over time so being compatible straight out off box saves us much hassle than having multiple plugins installed which can cause compatibility problems between versions etc.--.
