I brought 300 white tip .5, I am always skeptical of cart quality. I usually order from overseas to get a better price, but you run into cheaper made carts and a long wait time. Which results in loss of money in the end. So, is it really worth buying from a cheaper source? After purchasing these I realize its absolutely not worth it to go anywhere but vapepens wholesale. I have had no complaints with these carts thus far. Great quality and decent pricing. You can tell from just the weight of the cart to twisting the cap on that it is good quality. You get what you pay for which is a quality product. Not too mention instead of waiting for a month to get my product from overseas, I received my product within 2 days from the time I clicked purchase. I will definitely order from this company again!
