Faulty Coils

<p>I bought a box of coils for my twips aero. I gave one to my sister and brother as well. Our pipes are all bubbling and leaking into the battery. We were on the verge of going to buy new pipes when we changed coils and voila problem solved! Its not the first time you sell us faulty coils. That box is R220! One coild use to last about 3 to 4 weeks the coils you now sell last a week at the most. Why is the quality of your coils now so terrible? I know you guys are slowly discontinuing the aero but it shouldnt mean that the quality of it should drop as its still expensive!</p>
