I have been using the Demi model for the past two months. My previous espresso machine was the Spinn, which uses centrifugal force to express the coffee, and I was happy with that unit until it died. In general, I have been quite happy with the Demi unit, allowing me to make enough adjustments to dial in my coffee taste as I want it to be. The main reason for writing this review is that suddenly I couldn't grind any coffee as of yesterday. I contacted the company and got put through to tech support, which I have to commend in their expertise and patient guiding.
I was able to fix the problem with a minimal of trouble and got to know my machine on a deeper level. I deeply appreciate tech support that is available and knowledgeable.

Purchased the tk-02 less than 3 years…
Purchased the tk-02 less than 3 years ago, the drip function was not as advertised (essentially a slow pulled espresso) + now the grinder is not working and after playing 21 questions with support they tell me it's $350 to send it to some repair outfit to have it addressed. Incredibly disappointed after dropping ~$1500 on this, instead of the tried and true Jura.
Decent espresso drinks for awhile, I had 2.6k over the time period.

I really wanted to like this machine…
I really wanted to like this machine bad --- I got the TK-02 in November of 2025
I set it up and made a few coffees and was completely underwhelmed by the drinks - lukewarm and weak. I played around with the settings making the water the hottest it would go and the grind for strongest flavor -but could never get anything more than a lukewarm cup of really weak coffee --- I tried to get customer service help to see if there was a way to tweak it -- and they are extremely painstakingly slow to respond and incredibly unhelpful -- almost as if they studied how to get people to give up on asking for help. Pretty much right after i got it i started buying instant coffee and after i brew a drink i put in a spoonful - and then put it in the microwave for 45 seconds. I really studied a lot of different machines - i really wish this company hadnt tricked me out of $1800 I could have put towards a real automatic coffee maker

Not enough foam...
I rented a TK-02 for a month, hoping that I would like it enough to eventually purchase a unit.
Setup to first coffee was easy.
However, I quickly had to find out that the milk foam production was nowhere near expectations.
After trying a number of things (with assistance of TK customer service), the situation did not improve and I reluctantly returned the machine. Amongst the things tried......milk temperature (45F-95F), container (designated vessel, open container), milk beta setting (higher temp), different milk types (0%, 2%, whole).
The amount of foam produced never changed.
With a super-auto machine such as this, the whole point is NOT having to resort to an external device.
So, if you like your cappuccino on the dry side, this is not the machine for you.

TK-02 doesn't live up to the promise
TK-02 doesn't live up to the marketing
I wanted to love this machine but I just can't recommend it to others. Issue 1: it doesn't adequately heat/warm milk for latte's, my spouse uses microwave. Issue 2: the app is kludgy and flaky
e.g. when my Internet goes down -- i have to go through hoops to reconnect the app (though it says connected, it's not so schedules don't work) Issue 3: the amount of water volume consumed by starting/cleaning/sleeping is huge, means constantly filling up the water reservoir. Issue 4: you can have a lot of beans in the hopper - but they don't slide down far enough to get to grinder leading to yuck coffee.
I've done 275 brews - so gave it a good try.

Decent Coffee Machines, Subpar Customer Service
The TK-02 coffee machine itself is pretty solid. It looks nice on the counter. The convenience itself outweighs the fact the variable taste/quality of the drinks it makes. Even the espresso or americanos can taste a little different day by day.
What truly disappointments, however, is their customer support approach regarding an item in my order that took almost 30 days to ship. The rest of my order shipped for "free" and shipped quickly for delivery within <7 days, but for whatever reason, this cleaning/maintenance item that took a month to ship did have a shipping fee attached to it. Terra's shipping FAQ page, which was updated a couple of biz days after my order, clearly stated that the item should only take 3-5 days to ship out unless it was backordered. I was never notified that the item was backordered, with Terra ultimately claiming that this cleaning accessory was in super high demand and thus the long shipping time. Hard to believe a cleaning item is in such high demand...
Their support claimed to understand my frustration and acknowledged that the shipping time didn't match their own FAQ communications BUT still refunsed to refund the $8 shipping charge. I spent over $1,600 on a coffee machine, some bags of coffee, and cleaning supplies and they wouldn't refund 0.005% of my spend due to the poor shipping performance.
Being this rigid in their refund approach gives me tons of pause about recommending Terra to friends/family or making additional purchases from Terra myself.

Frustrated
First off, i’m not one to leave a review ever but my experience has been so frustrating that I needed to share. My customer service agent Eduardo has been trying his best, but i’m extremely disappointed with the product and company. I got this machine as a gift in 2021 and have loved it. However, i started having issues with it a few months ago and it’s been nothing but downhill since. I sent it in for repair once already, only for it to be broken again just a few months later. I’m now told they can no longer service my machine, and i have to buy a refurbished one. i had to push to even get $50 taken off that price. I asked for expedited shipping as it’s now been a month (after going back and fourth for weeks trying to find a fix) and they aren’t doing that either. For the cost of this product, it’s not worth it. please do better.

Hi Erica - thank you so much for taking the time to share this. We hear you. It’s clear the experience you’ve had- especially around the repair timeline and outcome - has fallen well short of what anyone should expect. We really appreciate your patience as we work with our third party center to get you back to brewing ASAP.

I can’t give a one-star to this product…
I can’t give a one-star to this product as the coffee it prepares is decent (not consistent, though). My problem was with the brewing unit; it had to be replaced less than a year after buying, and then it got stuck for a second time less than six months after being replaced.
The design of the machine is beautiful; however, the quality of the materials (remarkable for the brewing unit and all of the other parts that need to be washed) is very poor.
Customer service is not genuinely concerned about your problem; yes, they always start with an exclamation mark and ‘nice’ words, but that leads to no solution and very, very, very slow answers. God forbid if you send a follow-up email because you hadn’t received any response, because then you’ll receive a very ‘nice’ response saying that they being late to respond was your fault for ‘sending multiple messages’.
Finally, their solution was to offer me upgrading to the new machine trading in my old machine (which I agreed to, even though it meant paying 895 USD plus my old machine). But then they changed the terms of the trading-in value at the end, arguing that their ‘finance department had restrained their offers’.
Horrible experience. I will show you my machine being dumped at Staples for recycling so you can decide whether or not to invest 1,700 USD in a machine that has the slight possibility of being non-functional in less than 2 years.
My horrible experience with customer service was led by Gabriel, whom I’ve read here that is not the best at what he does.

Hi Juan,
We really appreciate you taking the time to share this. While it's never easy to read, it’s important. We're sorry the experience up to this point has felt like a letdown, both with the machine and the support along the way. That’s not the standard we hold ourselves to.
That said, we're happy to see that your original discount was honored and your TK-02 is on the way. We’re confident it’ll be a step up and can't wait for you to welcome it into your home.
Thanks again for the honest feedback. It helps us do better!
