How long will the GB-4000 last?
The GB-4000 is built to last a long time and 99.9 % of the instruments sold over the last several years are still working. Some manufacturers claim that their instrument will last a lifetime. We cannot and will not make that kind of misleading claim. We would be foolish to make such a claim. Any instrument that cannot be repaired, even after years of use, is replaced with the current model for only $750. No other company that I know of offers this kind of replacement in the industry.
