The site is well laid out so you can find the information on how to use it easily enough. All the options I needed are supported. The price is very good - you seem to get a low price with your very first purchase of credits so buy a good chunk with your first purchase. You can pay by PayPal which is nice if you're like me and you want to avoid giving your credit card info to too many sites. There's only one additional feature I might like which would be an API function to retrieve a log of mobile numbers, messages, times etc. However I don't need this at the moment so all in all I'm very happy with the service.
