Hi everyone,
At the moment we have two reported cases of a defective Terp Pen coil. One from the OP of the /r/waxpen post and another from this forum. We would like to thank the OPs for bringing this to the communities attention and for the further discussion. It appears that with heavy usage and time, the coil wire insulation comes in contact with the coil itself. This defect will be evaluated and the internals will be redesigned followed by manufacturing changes implemented to further prevent this from occurring.
In our tests and our engineer's tests, this did not occur in any coil. The images convey that the insulation slides down and contacts the element. We are still researching to see if this was a manufacturing glitch during mass production or if this was caused by forcibly pushing the coil into a glass dish or other surface, heavy use, or time. We do see this as something that needs to be reassessed and will do so promptly. From the coils we have opened and have been testing at our office, there have been none found to have this same defect. We have also been working with colleagues who have also expressed that their coils did not show this degradation.
Here are some tips to prevent this from occurring. Firstly, do not forcibly press the coil onto any surface as this can cause the coils to be pushed into the internals. We recommend to lightly dab the coil with concentrate by using a dab tool or pre-load the coil and proceed to use. Also, please take caution to leave some time for the coil to cool down between draws as this can cause the device to get hot.
Feel free to reach out via email to
Eric@bndlstech.com with any questions and if you would like to help us understand the situation with first-hand user data please reach out and we can either create a return label for your coil so we can inspect or we can take a look at a photo of your coil to give us a reference on actual user experience. Thank you for the continued support and please let me know if you have any questions.
