prezes thanks for the link. I’ve decided to bite the bullet and buy one. £39 delivered isn’t cheap, but I’m convinced the dosing funnels that cause a lip are likely going to create uneven water saturation through the Puck. I’ve toyed back and forth with living with the cheap one, but I’ve spent the best part of £2.5k on a new set up so it doesn’t make sense to jeopardise the end product on something as simple as this. It’s one of those things I hate having to buy, but I’ve got a feeling I won’t regret it in the long run.
