Question: Does it use the "old" kcup or does everyone in the office have to start buying new kcups
Document: Before I could start shopping for a new one, I noticed that my wife was filling the reservoir with water from the refrigerator -- thinking that the built-in water filter would be adequate. I realized that the brewer probably had some scale build-up from the tap, ran some vinegar through it several times, and it was good-as-new. So, now everyone refills the reservoir from the water cooler, and there have been no other problems to date.
Yes, you will spend some time perfecting the mix that is just right for you, but in the end, you will appreciate a perfect cip of tea/coffee, or glass of iced tea/coffee everytime. Very much worth the price, and you may end up discovering some new teas/coffees you have never tried before.One warning:  It appears everyone is correct in that you need to use filtered water in this unit.
We very much like the convenience of single cup brewing. This Breville sits next to our Breville electric kettle and looks great. Comes with assorted Kcups, and while we explore which Kcup brand we prefer, are consuming our Java One pod inventory by emptying them into the brewing basket provided. It's all good! EVEN BETTER, the 3rd & last Senseo to enter this house has left the building!
The start-up guide is easy and allows you to start brewing your coffee within 10 minutes. The built-in timer is a special added feature. You can program 'auto-on' and 'auto off&#34; and it includes an 2 hour auto shut off. I don't like clutter, even in the office, but this machine looks good and adds class to any counter.
My husband and I purchased this Breville about 2 weeks ago to replace the Keurig he bought before he met me, and which had crapped out on us (and caused me to swear off ever buying one myself!). The stainless steel really looks great on the counter.I LOVE that it works exactly how it is supposed  to--when making kcups! Love that it has 3 sizes for hot drinks and a 4th setting for iced drinks.
It is the software that goes screwy after while. Trying to get this back to normal has been so frustrating that we are no longer going to buy anything by this manufacturer. I DO NOT recommend buying this item, or anything by this company.UPDATE: It went out in the trash a few days ago. I am going back to the old-fashioned brewed coffee. K-cups cost, at least, 3 times as much as regular coffee!
I have had the Breville for 2-1/2 years. It works great. No more, stale hours-old coffee, a fresh cup every time. And everyone can have a different type...Caribou for me, then some weird flavored coffee my daughter likes, then a cup of Tazo tea, then decaf, all in about 2 minutes. Not bad. Okay, so, for all of those having problems. Check your water supply.
but since the other models also make a great cup of coffee I would say that it depends on the person. If your old coffee maker was a plastic Mr. Coffee then it probably won't make a difference (ot that there anything wrong with that, it's just that everyone has different tastes). If however you had a nice, stainless steel traditional coffee maker I think that you would be happy that you spent the extra money.
(Note:I also saw that Cuisinart has the new Keurig Kcup compatible SS700, which I also considered,but it has black sides instead of the stainless ones that this one does.It is also plastic in front, but it could be a contender if you are considering another option).Dont hesitate with this awesome coffee maker! !
Just want to start off by saying the machine worked great for 4 months and looks great! We purchased 5 of these machines for homes around our ranch after trying one at a friends house. The first one pooped out in the fourth month and the last one made it 8 months. When I called Breville to send it back for the warranty they informed me that I needed a receipt. Although the machine was 4 months old they would not warranty it because they could not tell the age of the machine.
Answer: The BKC700XL Gourmet Single Cup Brewer™ has been on the market for around 8 years.  In that time, the type of K-Cup® that it uses has not changed.
