Just copying my post from R/Espresso last year for context. I'll add another posts for my one year update.

Seen a lot of posts on this grinder and machine. Just wanted to add my notes as a new coffee drinker/maker

I started my search with the GCP but decided that the Profitec was the way to go given that it was similar price of a fully modded GCP without looking like it has been modded out. Overall I'm pretty happy with the Profitec Go it's pretty feature packed and well built at the price point, but there is a list of things I'd look for if I was looking for a new machine.

Profitec Go

• Really short working area. There's 74.68mm/2.94in clearance when using a bottomless Portafilter
• PID and Pressure gauge location. Being closer to the top and outside would be nice.
• No Preinfusion
• Knob placement for steamer would be more ergonomic on the side. Lever would be better than the knob
• Steam wand is not insulated
• The way the drip tray scrapes metal when pulling it out. Would be nice if one of the surfaces was lined with plastic.
• How the water refilled. This one is mostly due to the placement of the machine for me.

If I was buying a machine again at a similar price point again I'd take closer look at these:

• Ascaso Steel Uno Professional w/ PID V4
• Bellezza Bellona Dual Boiler

Was mostly a toss between Sette 270, DF64 and DF64P. Ended up with the DF64P since it seemed to be the better single dose grinder.

DF64P Grinder

• The way you have to zero it out.
• Drifting zero issue.
• The funnel rattling on the dosing cup
• Fork angle should be what the 3d printed mod is.
• Adjustment dial should be closer to the numbers.

I'll probably be swapping the DF64P out with a Niche zero, Timemore Sculptor, Lagom P64 or Kafatek Monolith Max. Would probably get the latter two used.
