I was a little concerned by the reviews saying it may arrive damaged, but mine arrived today in perfect condition.<br>The one I received appears to have been improved from that shown in the pictures - it has small dimple connections (picture) between the outer glass and the inner corkscrew glass spaced along the whole length; this should improve survivability during delivery and help with long-term durability.<br>Very happy with the quality and finish, StonyLabs will be my new go-to for glassware
Arrived well packaged, appears to be excellent quality and a perfect fit - StonyLabs will be my new go-to for glassware.
I was told it had a British plug and the right voltage but when arrived it had a 2 pin plug and was 110v! Unusable in the UK!!
It's really unfortunate that one of the beakers arrived totally smashed. The box was in excellent condition, it appeared to be well packed - but the 500 ml beaker was in pieces. The other pieces were fine.
