Overview
The new CF series offers compact refrigerated/heating circulators. With small overall dimensions the units can even be placed on a very small surface or within a complex installation. All models offer a heating capacity of 2 kW and safety class 3 according to DIN12876-1. The maximum ambient temperature of +40°C as well as ventilation air cooling allow installing the units very closely side by side with other units or directly under a fume hood. Furthermore all the models feature pump connections for external temperature applications and a bath opening for temperature control of small objects directly in the circulator bath. Wetted parts are made of high quality stainless steel or plastic. The instruments provide reliable Microprocessor electronics with high temperature stability as well as warning and safety functions.
Features:
- Ergonomic design and easy operation

Nice and fluffy, the color is a bit lighter
Size: 2' x 6' (Sheepskin Pelt Patchwork), Color: Light Brown
Pretty and fluffy. Wishing the color were a bit darker so it matched my decor better. It’s hard to tell what color you’ll actually get 🫤 Not ideal but doable.

Beautiful rug but smelly when you first unpack it.
Size: 2' x 6' (Sheepskin Pelt Patchwork), Color: Ivory White
Beautiful quality. Deep thick fur. The "patches" are noting more than where 4 or 5 inch splits, one at each end were stitched back together. I wouldn't have even called them patches. They are the same stitching as used to join the two pelts in the middle. The color is a very clean white. Being natural pelt, I was really expecting something a little more blond. I've bought New Zealand sheepskin several times before and I don't doubt this is Aussie or Kiwi sheepskin but I didn't notice this is processed in China before I bought it. Still, the only complaint I had was a strange chemical smell when I unwrapped it. It didn't smell like the tanning chemicals from previous pelts. But it's gone away after 3 weeks so I guess all's good.

Verified Real Sheepskin, High Quality, Looks Great
Color: Black, Color: Black
I was initially a little skeptical of the “real sheepskin” claim, so I really appreciated how much effort the seller put into transparency and verification.
This console cover comes with a detailed information sheet explaining how to identify real vs faux sheepskin using a burn test, and it also includes samples of both genuine and fake sheepskin so you can see the difference for yourself. That alone gave me much more confidence than most listings.
To verify the actual product, I carefully tested a very small, hidden area on the backside of the console cover itself. While the hair did briefly ignite (which initially gave me pause), everything else aligned with real sheepskin:
The smell was unmistakably burnt hair, not chemicals or plastic
The fibers did not melt like synthetic material
The burned area turned into soft, powdery ash, not hard or plastic like beads
Comparing my results to the included info sheet and photos, it clearly behaved like genuine sheepskin. Based on the smell, texture, and burn behavior, I’m fully convinced this is real.
The cover itself is very soft and well made. The black color is a true black (not faded or grayish), and it adds a nice upgrade to the interior. My daughter mainly wanted it for the look and the softness, and she’s been very happy with it.
It fits well on a standard center console and has stayed in place during regular driving. This should work nicely for most SUVs, sedans, and crossover vehicles that have a center console between the seats. This was for a 2019 Acura RDX.
Overall, this is a quality product, and the seller’s claims about authenticity were accurate. I really respect that they give customers the tools to verify it themselves.
Highly recommend.

The fluffer puffer console saved my clothes and is super cute in my car!
Color: Black
So soft and fluffy! The leather on my center console is scratched and ugly looking now and always causes tears in my knit sweaters! I was so happy I came across this, because I never even thought there was an option to save me (other than not leaning on my side arm when driving, which is so second nature I can’t help but!)…

Not for Honda Civics
I just want to start with saying that this is beautiful and very high quality. I really wasn’t expecting much with the price point being so low. But the cover is very soft and cozy. It is too big for my 2018 honda civic center console, I really wish it fit because I love this thing! I’ve just had it next to me while I sit on the couch and have been petting it the last couple hours. I’ll find somewhere else to put it because it’s that soft and pretty. If this will fit your car than I 100% recommend it!
