Tantalum Watches online and eBay store - any experiences?

Hi all,

Wonder if anyone has any experience of shopping with Tantalum Watches:

https://www.ebay.co.uk/str/tantalumwatches

http://www.tantalumwatches.com

Perfect feedback score on FleaBay (with a lot of sales), but no contact info on their website barring a contact form, which gives me pause...

Thanks,

Simon
