Aeolus Single Coil Drip Tip

Bought this as I like running a single fused clapton in some rda's, however this drip tip sits slightly loose and you feel the 'wobble' every time you puff, also may just be my version but it is slightly rough on the inside and it cuts o-rings up pretty bad, It destroyed an o-ring before I even got to puff on it. My overall opinion on this one is it would be great if they come smooth machined since they cost £10 for a drip tip... not to mention it's not really a snug fit, at £10 I would dodge this folks and get out the sellotape haha
