拆箱 Fitbit Alta
Fitbit Alta采用抽屉式白色和蓝色盒子，手感极佳。在盒子的正面，有一张带有所选腕带颜色(chosen wristband color)的产品图片。
包装盒背面包含有关产品的一些规格和营销文本(specs and marketing text)，以五种语言显示。当您打开“抽屉”时，您会发现一个带有磁性闩锁的浅蓝色实心盒子，手感很好，给人留下了良好的第一印象。(light blue box)在里面(Inside)，您首先会看到Fitbit Alta和配件盒。我们的采用Plum/Stainless Steel combination。
包装内含腕带、无线同步加密狗(wireless sync dongle)、充电线、保修和快速安装指南(setup guide)。
Fitbit Alta 开箱给用户留下了良好的第一印象。腕带经过精心包装，屏幕由可拆卸塑料条保护。包装中包含所有需要的物品，配件的外观和感觉都很好。(The Fitbit Alta unpacking gives the user a good first impression. The wristband is carefully packaged, and the screen is protected by a removable plastic strip. The package contains all the items needed and the accessories look and feel like good quality.)
设计和硬件规格
该设备本身看起来很有未来感，而且很轻。腕带上没有物理按钮。它有一个两管齐下的紧固系统(fastening system)和金属弹簧锁机构(snap-lock mechanism)，用于从设备上取下臂章。
设备的背面包含用于充电的触点，仅此而已。缺少心率监测器(heart rate monitor)变得很明显，因为这种传感器具有独特的 LED 系统，并且始终放置在Fitbit Alta的背面。不过，Fitbit Alta有(Fitbit Alta)HR 版本(HR version)，价格稍贵一些。
Fitbit Alta臂章有三种尺寸：小号、大号和特大号。要正确选择适合您的尺寸，您应该阅读本指南(this guide)。该设备具有一定程度的防水(water resistance)功能，但只能吸收少量的水，如汗水、雨水和水溅(rain and water splashes)。你不能戴着它游泳、洗澡或洗碗。您必须在此类活动期间将其取下。
Fitbit Alta提供三种颜色组合：黑色armband/stainless steel body、梅花armband/stainless steel body或黑色臂章搭配奢华的 22k 镀金机身。您还可以购买两种类型的皮革臂章（粉色和驼色(pink and camel)）和一种时尚的金属(metal one)臂章。
关于传感器，Fitbit Alta仅包含一个 3 轴加速度计。没有心率监测器(heart rate monitor)、高度计或 GPS(altimeter or GPS)，显然它仅用于基本监测您的身体活动。正如您将在稍后的评论中阅读的那样，情况并非如此。
Fitbit Alta还有一个振动马达(vibration motor)，它会在智能手机上有来电或消息时通知您，前提是您已将其与腕带配对，并且蓝牙(Bluetooth)已打开。
标准腕带由类似于许多运动手表中使用的柔性弹性体材料制成。(elastomer material)它会吸引灰尘和污垢，但由于它是可拆卸的，因此您可以轻松清洁它。不用担心生锈；扣环由不锈钢制成。
该设备有一个简单的OLED 显示屏(OLED display)，您可以通过“撞击、敲击或敲击它”或轻弹手腕来打开它，就像在手表上查看时间一样。除了时间和有关您的活动的信息外，屏幕还可以显示移动设备上来电的电话号码。(phone number)
锂聚合物电池的承诺电池寿命(battery life)长达5天，充电时间为一到两个小时。要为其充电，您必须使用包装中包含的充电线。您不能使用其他任何东西进行充电，因为该设备具有其专有的电源插孔(power jack)和一个简单但有效的夹紧机构(clamping mechanism)，可将充电器固定在腕带上。
为了向其他设备发送和接收数据，Fitbit Alta具有蓝牙 4.0(Bluetooth 4.0) 无线电收发器(radio transceiver)。该设备最多可以跟踪 7 天的详细运动数据（每分钟）和最多 30 天的每日总数。Fitbit Alta的应用程序支持(application support)包括Windows、Android和iOS。
Fitbit Alta 是一款外观精美的产品。就颜色和材料而言，它有多种选择，而且制造质量非常好。但是，技术规格表明该设备仅具有基本的活动跟踪功能，对于想要或需要(The Fitbit Alta is a great-looking product. It has multiple options as far as colors and materials go and the build quality is excellent. However, the technical specifications indicate that the device has only basic activity tracking functions and might not be useful for people who want or need to track )详细跟踪其日常生活的人来说可能没有用(their daily routine in detail)。

Review Fitbit Alta: A stylish fitness companion!
Fitbit has a wide range of devices for monitoring health and fitness activity. With a price tag at the time of our review of just under $100, thе Fitbit Alta is a reasonably-priced entry-level fitness wristband. Its main selling points are the pleasant design, the interchangeable armbands, the ease of use and its build quality. In this review, we take a closer look at the Fitbit Alta device and the Fitbit app that comes with it. Is it a worthy investment? Read on to find out:
What is the Fitbit Alta good at?
The Fitbit Alta is an excellent device for:
- People who value the looks and customization of their fitness tracker
- People who want a light, simple, easy to use device
- People who want a friendly interface that gathers the relevant data for their daily schedule and fitness activity
Pros and cons
Summarizing our findings, we liked the following about the Fitbit Alta:
- Stylish looks
- Simple to use
- Removable, replaceable armbands
- Excellent battery life
- Very good mobile ecosystem
- Affordable pricing
However, there were also some things that we did not like:
- It is not waterproof
- We found it difficult to put on and to remove
- Its measurements do not have 100% accuracy
Verdict
The Fitbit Alta is easy to use, a simple tracker which also happens to look great on your wrist. The armbands are detachable and replaceable, ensuring you can have a Fitbit Alta for every occasion. The mobile application interface is easy to use, compatible with most operating systems and provides a high amount of data. While its OLED screen is mostly there for show and is too small to be of real use, it does display the basics without sacrificing the battery life. Add to this the phone call and message notification feature, and you have a perfect device for people who need to monitor their daily activities, without being too professional about it.
Unboxing the Fitbit Alta
The Fitbit Alta comes in a drawer-type white and blue box, which has a premium feel. On the front of the box, there is an image of the product with the chosen wristband color.
The back of the box contains some specs and marketing text regarding the product, in five languages. When you open the "drawer," you discover a solid light blue box with a magnetic latch, a nice touch which gives a good first impression. Inside, the first things you will see are the Fitbit Alta and the accessories box. Ours came in the Plum/Stainless Steel combination.
The package contains the wristband, a wireless sync dongle, the charging cable, the warranty and a quick setup guide.
The Fitbit Alta unpacking gives the user a good first impression. The wristband is carefully packaged, and the screen is protected by a removable plastic strip. The package contains all the items needed and the accessories look and feel like good quality.
Design and hardware specifications
The device itself looks futuristic, and it is very light. There are no physical buttons to be found on the wristband. It has a two-pronged fastening system and metallic snap-lock mechanism for removing the armband from the device.
The back of the device contains the contacts for charging and not much else. The lack of a heart rate monitor becomes apparent, as such a sensor has a distinctive led system and is always placed on the back of the Fitbit Alta. However, there is an HR version available for the Fitbit Alta, which is slightly more expensive.
The Fitbit Alta armbands come in three sizes: small, large and extra-large. To correctly choose the size that fits you, you should read this guide. The device has some degree of water resistance, but it can only take small quantities of water, like sweat, rain and water splashes. You cannot swim with it, take a shower or wash the dishes while wearing it. You must take it off during such activities.
The Fitbit Alta comes in three color combinations: black armband/stainless steel body, plum armband/stainless steel body or a black armband combined with an extravagant 22k gold-plated body. You can also buy two types of leather armbands (pink and camel) and a sleek metal one.
Regarding sensors, Fitbit Alta only packs a 3-axis accelerometer. There is no heart rate monitor, altimeter or GPS, apparently making it useful just for basic monitoring of your physical activity. As you will read later in the review, this is not the case.
Fitbit Alta also has a vibration motor, which notifies you of incoming calls or messages on your smartphone, provided you have it paired with the wristband, and the Bluetooth is turned on.
The standard wristband is made of a flexible elastomer material similar to that used in many sports watches. It attracts dust and dirt, but since it is removable, you can easily clean it. Don't worry about rust; the clasps are made of stainless steel.
The device has a simple OLED display that you can turn on by "bumping, whacking or tapping it" or by flicking your wrist as you would when checking the time on a wristwatch. The screen can also display, besides the time and the information regarding your activity, the phone number of incoming calls on your mobile device.
The promised battery life of the lithium-polymer battery is up to 5 days and the charging time of one to two hours. To charge it, you must use the charging cable included in the package. You cannot use anything else for charging because this device has its proprietary power jack and a simple but efficient clamping mechanism which secures the charger to the wristband.
To send and receive data to other devices, Fitbit Alta has a Bluetooth 4.0 radio transceiver. The device can track up to 7 days of detailed motion data (minute by minute) and up to 30 days of daily totals. The application support of the Fitbit Alta includes Windows, Android, and iOS.
The Fitbit Alta is a great-looking product. It has multiple options as far as colors and materials go and the build quality is excellent. However, the technical specifications indicate that the device has only basic activity tracking functions and might not be useful for people who want or need to track their daily routine in detail.
