XGOGOP Set of 4 Clear Heat Resistant Oil Burner Pieces 14mm

All 4 showed up cracked @ and around the 14mm fitting and the same type. These fractures in the glass are clear as a pre-fossil fuel day. These cracks will surely grow quickly. I give it a week, maximum 2 weeks and they will all be broken. We'll see if I can turn this into a positive rating. I'll be waiting for a contact soon to see if they do the right thing and replace them with an undamaged product. Be nice to find a reliable 14mm glass product on Amazon.

I was disappointed that the glass was so thin. It broke easily. Other than that it worked pretty good

All but one came in broken.

Read all the way through-Broke about 4 of them. If they are bumped in anyway they will break. Like most pieces like this, because they are glass it is likely they’d break if bumped however these, if even slightly moved wrong they snap really easy. All them broke right below the skull part. HOWEVER, do not let this deter you from not purchasing them. They just need to be treated differently. These pieces are great. They are unique and good quality. So much that I would definitely buy them again. AND I will. I have not broken any since I made the adjustment of keeping them a little safer. Even in the beginning as they broke I was still set on the decision to buy more. They will have you excited about smoking again, time after time. The skull also acts as pockets, leaving you with that “extra” in short times. Do I recommend them? .. Would I had written all of this if I didn’t. But Them. Enjoy Them. and whilst using them you'll remember this review you read. cheers!
