I bought my P2 last May and am so pleased that I did. I have had so much fun realising my designs and I love the features like the dual camera and auto measure for the thickness of the materials.
The free software is good and improving all the time.
If I had the money and space, I would buy the apparel printer and the new metal laser cutter too. I love all the innovations that XTool are developing.

This is a great machine. Very easy to setup and easy to use. Being able to position your work accurately on the material using the camera is so much better than trying to frame it properly, like I had to with my original diode laser.
Initial setup is pretty straightforward but make sure you follow the instructions properly regarding the filling of the water and removing the transportation brackets. Note that you need de-ionised water, you can't just use tap water. Aligning the laser is also easy enough. I was pretty lucky that it needed minimal adjustment out of the box though.
I've had a couple of connection issues as I've got it connected via wifi to avoid trailing cables. One day it's fine, the next it would say that it couldn't connect until I connected it directly with USB or Ethernet. I think there's been an update since though, and that seems to have resolved the problem.
I bought this to primarily cut acrylic and it does that perfectly. Well, almost perfectly, some colours smell quite a bit and the exhaust doesn't quite seem powerful enough to make sure the smells don't escape into my work room.
The XCS software is improving with each release but it's a shame that it doesn't allow LightBurn to use the camera. I do all my designs in LightBurn, export them to SVG, import to XCS and then set up the cuts and layers there. It's a bit of a faff but I just can't get on with XCS for designing stuff. It's probably because I'm too used to LightBurn. If you haven't used LightBurn or a laser before then you should be fine with this machine and XCS. It's more than capable of cutting just about anything you'd want (it's not gonna cut metal but that's not what you're buying it for is it?)
So,
For:
Easy setup
Easy to use
Camera helps hugely with positioning
Automatic head adjustment so you don't have to worry about focusing it.
Nice clean cuts on everything I've tried.

Against:
Exhaust fan could be more powerful (I think they've improved this on the P2S so might not be an issue now)
Cannot use LightBurn fully (no access to the camera)
Expensive (but you do get what you pay for)
Very heavy so might be a consideration if your craft room is upstairs.

Arrived in time disappointed with the dirt mirror and cracked lens. Not sure what to do from here

I recently purchased the new P2S Laser, and I have to say it surpassed my expectations. It has nice build quality and is very easy to use.
Service from the company is also exceptional.

I recently purchased a P2. This is my first laser and I was pretty worried it would be complicated and I'd be figuring it out for weeks.
Not so.
It's so unbelievable easy to get going.
Out of the box. Add distilled water and you're away.
I'm so happy with it.
