They make your bike stop
Purchased to replace a XT 2 piston caliper that was previously installed. So lever and hose were already in place. Very happy, the brakes stop quick and have a great feel to them. Had evertyhing in the box to install, including proper screw for banjo fitting, new mounting screws etc.It did take a while to bleed. Had to remove caliper and turn every which way to get the air out, but thats not an issue with the product, but rather just an issue with a caliper that is bone dry to start with.

Best Brakes
4 Pistons are the way to go. Only a slight weight penalty over 2 pistons, but the stopping power is incredible. Easy to bleed and just plain work.

OEM shamans XT caliper and pads, no banjo fitting
This is an OEM Shimano XT brake caliper and N03A resin pads with cooling fins. It’s a great brake setup. Beware, the picture shows a banjo fitting. This is not included. Although it does contain the proper mounting screw for the fitting. Overall, very happy with the performance of these brakes once I ordered the banjo fitting I needed.

Good when they work, but fragile and unreliable
I have had several of these brakes - when they are working properly, they have great stopping power and everything is fine. However, they frequently have issues, and two of the three I have owned over the past few years eventually get stuck pistons. Since the pistons are ceramic, they are fragile and not repairable. These have just cost me way too much wasted time - would not recommend.

Scam/Junk AVIOD this company
Was a used part, leak from the pistons from day one, return the unit, sent back the same broken brake as a new replacement part. AVIOD this company...

The box was crushed when delivered and some of the parts looked used.
The box was crushed and the parts were loose in the crushed box. The brake pad spacer looked used with grease. It appears to be working but I am worried about longevity.

Had 4 of these in the last decade
I have had 4 of these on different bikes over the last decade.They are great in the beginning. However, after about 2 years unfortnately they all have had sticky calipers resulting in brake drag and leaking, leading to squeeky brakes and slip.BTW some of these were on bike I purchased, I would not have continued buying them...
