I bought this specific petg in black color, I use it on ender5 pro Bowden tube. It works quite well at 226 degrees with 6 retractions without stringing. The only negative is that it is quite glossy.

The Devil Design filaments have never caused me any problems with prints, whether with PLA or PETG, and I have tried several brands. For me, they are the best affordable filaments on the market.

It did not leave me satisfied...
With the Creality Ender Pro 0.6 nozzle printer, after many tests and different settings, unfortunately, it does not give me good results.
I would not buy it again.

From three different brands that I have worked with, I think this is the best of all. It works like PLA, but I don't know about the durability of the printed object. However, it worked well on both printers (one with a large bowden that had issues with other brands) without any fuss

I got it as my first material for an ender 3 v2 neo. With cooling off, 230c nozzle and 75c bed, 30mm/s outer layer printing and 65mm/s print speed, 6mm retraction and 40mm/s retraction speed, I have no stringing at all, and the bed adhesion is reliable up to a height of 5cm that I have printed. The black tends more towards dark gray and brings a little gloss, which in some parts that I sanded with sandpaper, became a nice matte finish.

PETG is great, I have tried black, red, and dark gray. I print at 230°C/80°C with a 0.6mm volcano nozzle and a layer height of 0.3mm. It adheres well to the print surface but requires a large and fast retraction of 7-10mm/80mm/sec to prevent stringing. Before, I used ABS with an open printer and had issues with warping and shrinking. Since switching to this PETG, I have been relieved. The only thing that bothers me is the shine, hopefully they will release a black matte version soon.

I don't know why it received such excellent ratings, personally it leaves "hairs" in the print, so it probably needs a larger retraction than 3mm. The Dark Gray that I tried has a glossy finish, so be careful if that's what you desire. I couldn't print with a steel nozzle even at 280°C, but I printed with a brass one without any problems at 245°C/80°C (and possibly even lower temperatures that I didn't try). However, I had detachments on objects with a small support surface, which can be solved either with rafts or by increasing the bed temperature to 90°C.

In terms of durability, it seems good to me, hence the final rating.

Very good! First time working with PETG, I didn't encounter any problems from the first print onwards!!

Highly recommended!

Excellent first time PETG glossy finish, ender 3 v2 -0.4 nozzle 250c- 75c bed Powder Coated PEI

Although it is my first roll and I haven't tried from other brands, I can say that it is quite good and easy to print. It has good elasticity and durability. For everything I have tried so far, I am completely satisfied.

Very good, the color is quite glossy and easy to print, at least it didn't give me any problems and I am completely satisfied, I work with it at 250/60

I had no issues with printing using the Prusa MK3. The only thing that bothered me a little is the packaging bag that does not seal airtight after opening.
