Better reviews?
Hrm, well, some Asian vendors have it priced as low as $30.99 at the moment. At that price point, I think it has gotten pretty stellar reviews. Hell, plenty of tanks cost more than that.

Also, at that price point, there are pretty much are no alternatives. Cheapest D2 I found is $40, Sigelei 75W is almost twice more than Koopor Mini and VTC Mini, afaik, has received more criticism than the Koopor Mini.
Then again, I started from a white page, without any prejudice against any manufacturer out there.
