Be wary of all of these. They all seem to be using the same adapters as the ones we've seen all over these boards up until now. There's nothing wrong with these adapters of course, but they're not aluminum and almost certainly won't match the space gray.
Tonsee store on eBay seems to be playing it shady. Every time you ask a question about an Apple Watch strap you get a convenient "out of office" type email. Because you know, an eBay store with over 70,000 rep doesn't have a team of customer service types processing orders and emails... :roll eyes:
Buyer beware.
