I've been using power chord for about 3 years now, but my favorite part is that they're always responding to requests with great speed! They are very affordable as well so not super expensive when you need it most (like we do).
Sometimes there's lag time between me adding an item or category change which can be frustrating since our website updates daily sometimes multiple times per day; however this isn't often nor have i had any issues reporting them directly through their contact form either - just keep in mind though if your looking at something specific like "How many views did X post receive?" then maybe wait until next month/week before updating? Also some of us run small businesses without much IT support staff / money available etc., hence why its important these things get taken care off right away instead waiting days later after posting new items because thats what.
