Absolutely HORRENDOUS experience.
People if you value your business, your website, your livelihood then stay FAR FAR away from these people.
I paid $259 to transfer my store over from magento to shopify, $259 is alot but im FINE with that if it worked out.
My biggest problem was when there app did not work well with magento even though they claim it does and all my "configurable" products did not transfer.
When i emailed them i did not get responses for 3 days at a time and when i did get responses you can tell they didnt take more then 30 seconds to look into it (or maybe they didnt speak english), meanwhile my entire site was down. After over a week of trying to get them to fix it i had to hire a local web dev local to do it.
I then emailed them thank you for trying but please refund me as i hired a local dev.
They would not refund my $259 for nothing! they said they cannot refund me it is against there policy.
STAY AWAY!, I SHOULD HAVE READ ALL THE OTHER REVIEWS BEFORE GOING WITH THESE PETTY INTERNATIONAL CROOKS.
