Is this authentic martin kastler or replica; judging by the so-so reviews, i'm thinking replica?

I have two of these. One purchased directly from Crucial Detail / Martin Kastner, and one from Amazon. Same product / no concern of replica. Minimal difference in price, so if you still have concern, just order from Crucial Detail directly.

How do you sterilise this product?

Thank you for being part of our Porthole community. The Porthole is dishwasher safe and can also be steamed for sterilization.

My porthole infuser leaks, what can I do?

Hi. The best way is to contact us at Crucial Detail at info@crucialdetail.com for troubleshooting and replacement parts directly.

How do i get the glass off? Ive removed both hex screws but the glass wont budge... Halp!

Thanks for being part of our Crucial Detail Porthole community! Here are a couple tips for removing the glass when it is tight. Quick Tip: Cover screw holes with fingers and blow air into the Porthole spout with mouth to release the tension. Longer Term Tip: The plastic will loosen with use. Lay the glass flat on the counter (on a towel to avoid damaging glass) and insert the body over the glass with a bit of force. Then push the glass back out, repeating the whole process a few times on both sides before using with liquid.
