I am extremely disappointed with this product, which seems to be a generic, low-quality item. I am baffled that a brand like Gomechanic would sell such subpar products. It functioned adequately for only about three weeks, during which it was used for a mere 4 to 5 hours in total. Suddenly, it stopped working altogether. This purchase has been a complete waste of money. To make matters worse, there is no option to return the product, get a refund, or even request a replacement. This has been the worst purchase I've ever made. I strongly advise against buying this product.
