metals that retain a high order of ductility and resistance to brittle fracture down. to very low temperatures, and a much larger class of metals that, at some temperature. or in some range of temperature, undergo a transition from ductile to brittle.behavior. As pointed out above, the temperature level where this transition in fracture behavior. occurs is influenced by the test conditions.
If you are a moderate vaper, whereby you vape fairly consistently through most of the day, but only take a couple drags each time, your coils should last you about 14 days or so. If you are a very light vaper, where you take a few hits here and there throughout the day, your coil could last you 3 weeks or so.
Gels generally last 2-3 weeks. The best part about gel manis is how long they last. If you have a bunch of events coming up back to back like prom, internship interviews, and family vacays, gels can be the perfect solution because they last about two full weeks with no chipping. Keep in mind, thought, that how long they last does depend on your body chemistry, the product itself, and how it's applied.
