The custom service is good and sent me a replacement immediately after I wrote the previous review. However, the new one broke again after one day of use. My electrolyte is 0.1M KHCO3 and the holder is used for working electrode.
Dear Customer,
We are very sorry to hear that your replacement unit broke again. We sincerely apologize for the inconvenience.
Please contact us directly, and we will issue a full refund immediately. In addition, we are reviewing this product carefully and taking steps to improve its durability and performance, so that similar issues are less likely in the future.

After using for only a week (not every day, probably three times), this electrode is already broken. Poor quality.
Thank you for your feedback, and we’re sorry to hear that you’ve had an issue with the electrode. To help us understand better, could you let us know if you were using any strong acids or bases with it? These can sometimes affect the electrode’s performance.
We’ll arrange a replacement for you right away. Please let us know if that works for you!
Thanks again for sharing your experience with us. We’re dedicated to ensuring our products meet the highest standards of quality, and we truly appreciate your support in helping us improve.
