We know how frustrating and time consuming it can be to change a heater. This product is a consumable and as such has no guarantee, much like tires of a car. 3D Solex's heaters are individually tested to withstand one year of use.
Item Specifics Wattage: 40W Weight: 0.020 kg Size: 6 × 3 × 1 cm Warning: May not work in “Olsson Block” clone! The calibre of the sensor holes are sometimes out of spec. They need manufacture to tolerances within 6/100 of a millimeter. If the hole is too large, the heaters will not be able to transfer energy, and burn out very brightly inside your block!
