Very very good. Good build quality. Recognized immediately and worked perfectly. Buying more! Goodbye HDMI!

Well made product. Works great! Cord length is adequate and is a great value!

Works as advertised.....no problems and faster than I need.

This product specification is currently not available for sale in Korea.I happened to find out that your company sells this product, so I decided to make a purchase.Since I had to receive it through international shipping, it took quite a bit of time.However, considering it was international shipping, the delivery was surprisingly fast.I used this product with the Thunderbolt port on my 2017 iMac Pro.Amazingly, when I used this cable with a Thunderbolt eGPU dock, I noticed no issues whatsoever.It worked perfectly.I am not just satisfied with this product.It made me interested in purchasing other cables sold by your company as well.However, I was disappointed to learn that the products I want are not currently offered by your company.The items I’m looking for are a USB-C to HDMI Converter, USB-C to HDMI cable and a DP to HDMI cable.If I hear that your company starts selling these, I’ll come back immediately to place an order.이 제품의 규격은 현재 한국에서 판매되지 않습니다.마침 귀사에서 이 제품을 판매한다는 사실을 알게 되어서 구매를 결정했습니다.해외 배송으로 받아야 해서 시간이 많이 걸렸습니다.하지만 해외 배송이라는 점을 감안하면 배송이 놀라울 정도로 빨랐습니다.2017년형 iMac Pro의 썬더볼트 단자에 이 제품을 사용하였습니다.놀랍게도 썬더볼트 eGPU Dock에 이 케이블을 사용할 때 아무런 문제가 없었습니다.완벽하게 작동했습니다.이 제품에 만족한 것뿐 아니라 귀사에서 판매하는 다른 케이블도 구매하고 싶어졌습니다.하지만 제가 원하는 제품은 현재 귀사에서 판매하지 않는다는 사실을 알고 실망했습니다.제가 찾는 제품은 USB-C to HDMI 변환기와 USB-C to HDMI 케이블 그리고 DP to HDMI 케이블입니다.귀사에서 이것들을 판매하기 시작했다는 소식을 듣게되면, 나는 즉시 주문을 하기 위해 돌아올 것입니다.

This 1.2m cable is one of the longest 40Gbps 240W passive USB-IF certified cables on the market. At the time of writing it is priced at about $20. This cable is USB-IF certified, meaning at has been tested by a USB Forum approved test facility and adheres to all the required performance characteristics of a 40Gbps 240W cable. Far from all cables are qualified this way.This cable also correctly identifies itself as a Thunderbolt cable and will correctly function with all your Thunderbolt 3/4 devices.It will also function properly as a video cable (carries DisplayPort Alt Mode data).As an added bonus, since this is a passive cable (no active circuitry to re-transmit high speed signals) it is expected to be fully compatible with future 80Gbps and 120Gbps USB4 modes!As for construction, the outer material is a cloth braid and has an adequate amount of flexibility for a 40Gbps cable. The cable insertion force is on the lower side but the retention force feels high enough so the connection is secure. Cable Vbus+GND resistance is measured to be about 125mΩ - plenty of margin left from the 150mΩ specification limit for 5A (240W) cables!My issue: the emarker contains some inaccurate information (but this should not affect performance).- The USB Vendor ID field is set to 0x2E99 (11929 decimal) which is Hynetek's VID, but it should be 0x3678 (13944 decimal) for Silkland's VID.- The Cert Stat VDO field is set to 0x23A5 (9125 decimal) which corresponds to the Test ID for the Hynetek HUSB332D emarker chip, which is the emarker used in this cable. It should be set to the XID assigned by the USB-IF to this cable: 0x281C (10268 decimal).- The Product VDO field is blank. This could have allowed Silkland to program a unique identifying value and release number to this cable to track future cables that potentially address the above issues.These issues shouldn't have made it past the certification process or Silkland's engineering department in my opinion. I have contacted Silkland directly, and support claims they will update the cable programming in future batches but they are unable to send me a sample as evidence.Also, note that only the 1m and 1.2m versions of this cable are USB-IF certified.

These cables are outstanding. insanely fast data transfer and charing speeds. decent value too! Will certainly be purchasing again

This cable was purchased to charge the battery on a JBL 770NC wireless headphone set. The cable is sold as a Thunderbolt x Thunderbolt connection. The whole point of a Thunderbolt connection is that it should work no matter what direction you plug it in. With this cable, the Thunderbolt has to be put into the headphone set in a specific direction, or it doesn't charge the batteries. The cable is also extremely stiff and cannot be coiled to a reasonable size. This was a very expensive cable, and is unfit for duty.

This Thunderbolt cable helped with migration from an old iMac to a new one using direct connection instead of wi-fi.
