Latest price update (UTC time):
Banggood (22.99 USD)
Banggood warehouse is located in China. So I have checked for active coupons (all category coupons and old ones), but there was no working coupon in Banggood. You probably want to know if this is a good price. Pretty sweet, this is the lowest price I have ever noted for this product!
