“The lifespan can vary depending on the thickness/sweetness of your juice but on average will last over 4 days of vaping. I've had a coil last over a week and another get a little burned out in around 5 days. 35w is a safer bet for these. For a pack of 5 you can't complain”
“These coils are good. 55w is a bit much, but they hold up. 55w is the suggested wattage for my device and they last over 5 days with fairly heavy use. I usually change coil after a week regardless to avoid any burnt taste or muted flavour but these were still in decent condition after a week. I would probably recommend the 0.3 more for the 40w region if you're vaping 10mg Nic salts.”
