Yes, this product is insanely expensive, but if you have a problem with a bad connection, go for it. If it still doesn't work, you can return it. As for me, I had a flickering issue on my 12" MacBook and 24" LG Retina 4K monitor with the included cable, which they made available a year later. The connection got better and worse as I tried the 0.8m white Apple Thunderbolt cable, suggesting that it might be a cable issue. This has not caused any problems and I am very happy with my investment.
