So it's been a week and a half since ordering from them. I emailed about 5 days ago with zero reply. Are they pretty unresponsive?

 

One tip...it's not Amazon.
Hate to have to say that...but with smaller operations, you have too keep in mind, things can take time.
Some items, like the hk enabler are semi custom...and while they are "ordered" as an off the shelf item, can take a few days for their supplier to get it to them...kinda like the ian's auto up window circuit...
Think most folks needed about 2-3 weeks to get stuff from England for most prior posts at best.
Do try to get verification that the credit card WAS charged and the order went through....
The site does have lots of folks that have used it for hard to find items in the last decade....

 

Yep, I'm not an idiot, I know it's not Amazon. As someone who owns a small business I couldn't imagine not replying back to a customers email. It really doesn't take much more than a couple minutes to reply back. Just basic customer relations skills I guess.
