Just received my band. It came with a tempered glass screen protector and a stylus.
The feel of the "leather" is very similar to the Apple Leather Loop. It's surprisingly supple and the "grain" is VERY similar. It is not stiff, like I expected from the previous pictures. The red of the band is similar to the red on a Netflix envelope, included in the picture.
I specifically requested the medium length, and it is identical to the Apple band in length. The only differences in looks are that the end of the long piece of the tap is a little larger and the metal-lined opening on the short strap is slightly less rounded. I tried to get this in the picture but it's hard to see unless you're looking close up. The edges of the band also doesn't come all the way to the edge of the Apple watch like the authentic leather loop does - it's about half a millimeter short on either side.
I was very impressed until I put it on. The magnets inside are noticeable weaker than the Apple band. Typically when I make a fist the Apple band gives me some resistance but moves slightly (I do this when I put it on to the settle the band between magnets so it doesn't loosen over the day and give false positive notifications). The SIKAI band gave me little to no resistance and the magnetic connection loosened quickly. The magnets seemed strong enough to keep it on during normal wear.
However, in a test where I flailed my arms wildly (kind of like Dr. Zoidberg on Futurama) the SIKAI strap loosened very quickly. The magnets reattached themselves, but it's a scary thought that it
could fall off this way, however unlikely that motion might be in normal circumstances. It's important to note that the Apple band did not loosen at all in the same Zoidberg test.
For a knock-off, it's not bad - but I wish the magnets were stronger. Not to sound morbid, but I also wish it were more of a blood red, like the (Product) Red iPod shuffles and nano used to be.
