Reviewers praised its compact size and considered the rounded form of the device to be interesting. The quality of the screen was considered to be average, and its keyboard to be comfortable to type on. The reviewers liked the features and ease of use of the device, the fashion design, and that it had many features for its compact size, but didn't like the slow application loading speeds, the storage, and the clip-on camera, saying that the viewfinder of the camera is inaccurate, and the photo processing speed is slow.
