These high-grade Titanium Heat Breaks are an upgrade to the stainless steel Heat Breaks that come as standard with E3D V6 HotEnds. Since V5, the manufacturing processes for all E3D HeatBreaks has been overhauled to achieve a better internal surface finish than ever before. The improved internal surface finish helps to reduce extrusion force and improve reliability on retractions. They are capable of reliable high temperature performance for many years, but are somewhat delicate due to their fine machining These special HeatBreaks are additionally made from Grade 5 Titanium. This material is exceptionally strong and has lower thermal conductivity than stainless steel, allowing you to keep the cold side of your HotEnd even colder. This creates a more sharply-defined meltzone within the hot side, creating greater extrusion control. The increased strength of these breaks means that they are also much less likely to crack or snap, either while hot-tightening or on the occasional accidental collision with a printed part or printer bed. Upgrade your 1.75mm V6 HotEnd with this aerospace-grade HeatBreak!

Deceptive marketing.
So as for the item itself, it works exactly as intended. The problem is this company seems to enjoy ripping off customers so I hope this review will help someone. This listing is for only 1 single heat break. Which ok this would be fine if a bit deceptive since the picture shows multiple. The problem is they have another listing which has 1 in the picture and even says it's only one, for half the price.Genuine E3D V6 Heat Break (1.75mm) (V6-175-BREAK) https://www.amazon.com/dp/B077Y2MHW8/ref=cm_sw_r_apan_glt_fabc_QSPTSQ5B71T9VXPY2AF6I'm disappointed in this company.

You only get one
Works great, but you only get one in the package not two like the picture shows.

Only 1, not 2 as shown in picture
Looking at this item, the picture shown implies there are 2 of these. There is only 1. Yes, buyer beware, especially when Amazon is concerned

Causes retraction-related jams on Prusa MK3
I have a Prusa i3 MK3. It is a well known issue that these printers made before a certain date had a heat break with a machining issue that caused filament jams and poor extrusion. So like many others, I decided to just replace the heat break. Initially I intended to buy a normal E3D V6 heat break, for about 1/3 the cost of this. After hearing about the titanium heat break, I decided to go that route instead. I now wish I had never heard of this product.Titanium has a much lower thermal conductivity than the steel used in the regular heat break. This might seem like a desirable characteristic, given the purpose of a heat break is to minimize heat transfer from the hot end up into the heat sink. However, it also causes less heat transfer from the heat break to the heat sink. Because of this, when the printer performs a retraction move, molten filament is being sucked up into the heat break. This then causes a temporary jam, which can be seen as a void in the print.So do yourself, and your wallet, a favor, and just get the regular stainless steel E3D heat break.

Out of spec
finish of the product was very nice but the critical bore was over size. hotend side bore is >= 2.15mm and the heatsink side is ~2mm. so the critical part of the heat break is something like 6-8% larger than it should be. Checking the e3d spec sheet it defines the center bore to be 2mm for the full length so this is very much a production/QC issue.

It works
As described, only one that could be packaged better. Part fits well and is working.

Makes a difference! Installation/removal tips below
I highly recommend using Slice engineering’s Boron Nitride thermal paste when installing this. The two work well with each other and there is a noticeable increase in print quality. Also, if you have tk remove for some reason: there is a product called “glass running pliers” that are used for splitting glass/plexiglass after scoring. They are basically pliers with rubber grip covers on the end. Its a perfect tool for removing a stuck throat like this one without marring the threads!
