This automotive accessory is a game changer for anyone who has experienced the frustration of trying to find a secure grounding point on their car or truck... After I put it to the test i was impressed by how strong the magnet held to any metal surface and the ease in which I could connect my grounding wire. The one downside is that it may not be suitable for larger vehicles as the magnetic grip may not be strong enough. Overall, I highly recommend this product for anyone looking for an easier and more efficient way to ground their vehicle during maintenance..
