"It's gorgeous, but it's not flawless," writes The Verge's tech reviewer of the iPhone X's design, and the sentiment could be used to describe most overall reviews of Apple Inc's (AAPL) - Get Apple Inc. (AAPL) Report much-hyped new device.

On Tuesday, the first-look reviews for the smartphone, Apple's most expensive ever, started to come in, and most were complimentary, although many noted there were still some kinks to work out and that the $999 price tag is undoubtedly steep. The news that iPhone X pre-orders seemed strong and supply was not as limited as feared, based on shipping times, helped propel Apple's stock 2.3% on Monday, and shares were up an additional 1.6% to $169.30 on Tuesday afternoon.

The Verge's review by Nilay Patel praised the iPhone X's design and new OLED screen, but panned the notch at the top that contains the phone's new sensors. Patel also noted that Face ID accuracy can be spotty in certain bright light conditions, but worked well indoors. He called the new animoji based on a user's photo "probably the single best feature on the iPhone X." The review concluded that "if you're one of the many people who preordered this thing, I think you'll be happy...But if you didn't preorder, I suspect you might not feel that left out for a while."

Mashable's Lance Uloff called the iPhone X fast and powerful, and praised the quality of its front and back cameras. He also noted that Face ID works well and successfully thwarted several different attempts to fool it, although it couldn't distinguish between identical twins. Uloff concluded that "yes, the iPhone X is expensive and it removes a beloved feature [touch ID], but it innovates in key ways. It's still the iPhone you want" and said even if you pass on buying one now, it represents the future of the iPhone.

Buzzfeed's Nicole Nguyen said that the new iPhone offers a great all-screen experience, excellent cameras, and decent battery life. But the killer feature, according to Nguyen, is the smaller size compared to the iPhone Plus phones, which is much easier to handle and use for people with smaller hands and pockets. Because of the X's edge-to-edge display, its actual screen size is the same size as that of the Plus, even though the overall phone itself is smaller. And the X also contains the more sophisticated two-lens camera of the Plus phones.

Nguyen noted concluded that the X is "really only for people who use the *heck* out of their phones. I'm talking about a ton of photo taking, video shooting, social-media performative exhibiting, gaming, web browsing, etc. This is a device for a power user, not a casual smartphoner who texts and uploads an Instagram every once in a while."

Pre-orders for the iPhone X started last Friday, and the phone will go on sale in stores this Friday, Nov. 3. More in-depth reviews based on lengthier testing periods should be out in the next day or so.
