Ebay - exploding GU10 LED bulb

I've recently bought some LED GU10 bulbs for the kitchen, thinking that LED bulbs would last longer than those cheap bulbs from the supermarket.

These were from a UK seller on Ebay.

















To say I'm shocked at the exploading bulb after a couple of days use is an understatement.

The last image shows the top of one of the bulbs.
The right hand side of the dome feels as if it's been seated more into the casing. I'm not sure if these are hand made, or just generally poor quality, but these are dangerous.
