I live in the US and I have shopped on HeliPal for close to a year now with no problems. In fact, many US sites buy from there and resell in the US.
However, I recently purchased my first scale from the site and it has been a nightmare. After researching the boards, I discovered I was not the first to suffer from this issue and finally contacted technical support. After 3 or so emails back and forth, their spokesman, Jacky told me it sounded as though the heli receiver was bad and I needed to return the heli for them to confirm. No return information was ever provided. After several weeks of my emails going unanswered, they finally contacted me once I involved PayPay. The company claimed they had lost contact and just recently found all my missing emails.
I wish I could say the issue is resolved, however it is not.
Bottom line, although expensive for shipping, HeliPal is the place to shop. However, buyer beware, if you need support of any kind, you are on your own. Hence my 3 star rating.
