3 of the last 4 plugins I purchased from them were either not as advertised, broken or in one case, took down my entire website. Requests are ignored and if you file a claim with PayPal they lock you out of the account including items you had previously purchased.
Tip for consumers: Not worth it. Stick with free Wordpress plugins. In most cases you can get the same features with better written code and fewer headaches. Even if the free version of a plugin works, the paid version often does not.
