Love this drip dispersion device for lowering agitation in the 2nd half of my pour overs. Like some others who have bought the Gabi, the holes in mine weren’t all the way “opened” when I first received it but it’s quickly fixed by poking around with a tweezer

Loved so much I bought another for work

While expensive for what it does, the Drip Master B works very well. I am using it with the ceramic Kalita Wave 185. Makes it easy to get reproducible pour over coffee brews. Note that when I received the second Drip Master (gave the first to my brother) I initially had problems with the unit only draining at 0.5 grams per second. This led to a pour over that took six minutes rather than 3.5 minutes and the coffee was over extracted. The first one I bought was about right at 1.5 grams per second. For the slow draining Drip Master, I ran a lot of water through it, washed it with a lot of dishwashing soap, then thoroughly rinsed it. After that it is draining at 2 grams per second, which I understand is the proper drain rate.

As above, coffee brew/drip quality is fantastic. But the upper funnel portion with the handle broke within 6 weeks of intermittent use (at my condo. There about half time. Cracks appeared and it leaked. I contracted the manufacturer and they could not have cared less. Absolutely no idea of what customer service is. My Aeropress I used for 3 years before getting this, is now back in use. Avoid this product. The cracking issue is not uncommon. I always hand washed, never dropped it. The plastic material is fragile.

I was hesitant to order this with the reviews regarding the drainage issues, but decided to roll the dice, anyway. Well, like the others, about half of the holes are not draining any water, which is pretty disappointing. I'm planning on poking the holes with a needle, like the other reviewers said, but I'm uncomfortable with modifying a device that is supposed to be 'precisely calculated' in design. I guess I'll just have to compare the flow rate afterwards, and hope it dispenses water close to the 2g/sec.

With that being said, I really think this is a cool product and I'm excited to use it. I would even consider ordering another (assuming the manufacturing issues are remedied), just to know that I have a properly functioning device - not something that I just hope is working as intended.
