This Aspire K1 has the new style of coils. The bottom vertical coils featured in them give a better performance and are more reliable than the old models were. It is made of stainless steel and glass and has a 510 drip tip which is removable. It is thought to be one of the best clearometers on the market for the price as it is a budget model. With the new coils it means that the flavor of the e-liquid used is much better and there are really great vape clouds produced as well. The clear tank means that you can see how much liquid you have left and it is well constructed to make it durable and sold. It also has a great slim design which makes it easy to store or carry around and works with eGo-Sized batteries. Therefore it offers a really great value for money too.
