Some online reviewers of other company's shells pointed out that they were lumpy but yours is perfect! I honestly do not know if its possible to create a voltage surge though the car electrical system by shorting the positive terminal to ground, or by drawing sparks just when doing a normal correct connection to the battery.

Wear Protective Gear: Use gloves and safety glasses to protect yourself from battery acid and debris. The handle and leading edge of the tool are both insulated to help protect against unintended metal to metal contact that causes the sparks to start flying.This spanner has a good weight to it and feels robust, how the ratchet mechanism will cope in the long term time only time will tell. I think the issue is the lack of foresight by MG (this is a common theme) to not have an accessible hard power reboot switch. I think it is because if you sat in the car while it is charging with the radio on, after a time it will shut off so I hit the start/stop to turn the radio back on. I don't want to sound impertinent, but there is NO-WAY the 10mm nut is welded to the terminal clamp - and there is certainly no corrosion visible that could cause a problem. The arm profile actually is a great design, the geometry of the mirror itself is kick ass, the tinted mirror glass is super cool, and the gradient of blue to black was a really nice touch.

When I first saw your pricing, I was skeptical, but I had kind of a problem in that the handlebars on my 80 XS650 were a retro style that most mirrors did not fit well and the bike has a custom paint. Owners have experienced problems when trying to drive away, after pressing the START button, then switching the gear selector into reverse or drive BEFORE the car has fully booted into the READY status. You still have to connect it to your battery and run the small cable (smaller than an electric lamp cord) out of the hood and through the closed door to the solar panel that sits on the dash top.

It might help if you mention what vehicle as I must admit I don't understand what type of terminal you have. Safety: Using the right size wrench reduces the risk of slippage, preventing potential injuries or accidents. If the nut is very tight you might be better off putting another open ended spanner on the square head of the bolt so you can stop there being too much force on the battery terminal itself.
