I'd like to first thank Keystone Vapes for their innovative high-puff disposable model vapes, particularly the Keystone Cybertank 40K Puff e-juice of 40mL visible tank with a 1100mAh battery. I recently purchased the Cybertank 40K Puffs variant model from the local convenience store & was very ecstatic in obtaining one. Unfortunately from my experience, despite the innovation of the vape design; it short-lived after only having two strong pulls/ hits & stopped performing which currently deems as a brick. As a first-time user & certainly the last one using the brand; I'm regrettably unsatisfied with the performance of the product & disappointed with delivery result of Keystone Engineering. I personally wouldn't recommend this product to anyone & would strongly suggest other brands like e.g. Nasty, Elf Bar, Oxbar & etc, as they meet the users expectation.
