I like that it's very easy for anyone who has no coding experience at all, even if they have little knowledge of CSS or HTML can use this plugin without much trouble! It is also extremely customizable in terms what you want your slideshows look/feel-wise so there are many options out here which makes creating them fun too (and not boring).
Sometimes when using bXSlideR some elements don't load properly - perhaps due having other plugins running? Other than those few issues everything else works great though!! We're able create beautiful sliders with only basic html / css skills but still be easily editable later down by our clients themselves as well because we give full access via FTP etc.. The fact their customer support team responds quickly helps us solve problems faster while working together through email instead over phone lines sometimes takes longer since its more difficult getting across language barriers especially.
