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.

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.
