RUIYITECH Replacement Pyrex Rainbow Transparent Glass Tube Bubble for Uwell Crown 4 IV Tank Crown 4 RTA Atomizer (3 pack) (Rainbow)

I accidently broke the glass on my crown IV for about the third time so i ordered these hoping they would be suitable and i'm glad to say they are as long as you have the chimney extension already! the box contains 3 replacement glass tanks but they do NOT include any chimney extension i fortunately had a couple from previous individual replacements i've had that did come with it.Does the trick, fits perfectly fine and it's handy having spares on hand because reverting back to 2ml glass is torture.

Great glass, nice to have some different colours on the vape for once. One thing I will say, this product is for people who have already been using bubble glasses and are looking for a replacement, as you need the chimney that comes with the official bubble glass in order for these to fit your tank. One cost roughly 5 euro. These are great for somebody like me who just keeps breaking glasses!

The bubble tank is the size I needed for my tank but not overly impressed. The reflective design on the glass makes it hard to see the liquid volume in the tank. Cert to get a dry hit more than once. They will do until I getva clear glass replacement

Really good product but be aware that you need chimney extension for the 2ml uwell crown 4 edition.

Absolutely shocking doesn’t fit my crown four tank at all like it said it would waste of money !!

This 5 mil tank Fits perfectly if u have the extension only problem with having the rainbow effect is you cant see how full it is especially when filling as well as when vaping

Nice glass but unfortunately does not fit the tank in description I have the uwell crown 4 and it’s not compatible I have to pay for an extension which they should’ve maybe included it in the description.

unfortunately didnt come with chimney which is needed.
