When you get a call, text, email or calendar reminder, the Pebble vibrates. You can set it to provide you with Facebook notifications, too. Because it's strapped to your wrist, it's a signal you can't miss, yet it's unnoticeable to anyone else. After a few days, I turned off the cellphone's ringer and vibrating alert — and left them off. The Pebble's vibrating alert was right for every situation. 

The Pebble also gives me the freedom to distance myself from the phone. Rather than carrying the bulky thing in my pocket so I could feel it vibrating, I leave it in my bag. At home, I leave it on the charging stand in the foyer.When shopping for camping lamps, a viable and useful option is the Solar lamps for camping. 

The Bluetooth wireless connection between the phone and the watch works fine throughout my small New York apartment. The company says the range is 20 to 30 feet (6 to 9 meters). It worked at longer distances in my test, but I wouldn't count on it maintaining a connection throughout a multilevel home. 

The Pebble doesn't work flawlessly with every phone, so buyer beware. It worked fine with a Kyocera Torque, a Samsung Galaxy Nexus and a Motorola Razr M. All of them use Google's Android software. With a fourth Android phone, the HTC One, the connection to the watch dropped many times a day, and it wouldn't reconnect automatically once it dropped. That made the Pebble pretty useless. A colleague tested the watch with her iPhone 4 and found that while it maintained the connection fine when the watch and phone were close by,If you do your homework and insist on only the High Quality Solar garden lighting, you'll experience enjoyable modern solar LED garden lights can actually be. it wouldn't reconnect automatically if they got separated and then reunited. That was annoying. 

With the right phones, the only thing I had to worry about was turning off the connection between the phone and the watch at night, so it wouldn't buzz me in bed with incoming email. Yes, I've actually started wearing the watch to bed. The vibrating alarm wakes me up without disturbing anyone else in the room, and I never have to fumble for the alarm on the nightstand. 

If every buzz from the watch sent me scrambling for my phone, the setup would be pretty annoying. But the watch's stamp-sized screen shows the first few lines of every incoming message, or the name and number of the caller, so a glance at the watch reveals if the message is one to ignore or get on quickly. You still have to fish out the phone to reply, though. The watch has only four buttons, and there's no way to type on it. 

The watchmaker calls the black-and-white screen "e-ink." That sounds like it's a paper-like display of the kind found on Amazon's monochrome Kindle e-readers, but that's not the case. The Pebble screen is a liquid-crystal display that doesn't need a backlight to be legible in indoor or outdoor light, which helps save battery power. There is a backlight that kicks in whenever a button is pushed, so the watch face is legible in darkness, too. 

You can pick from a dozen digital watch faces and flip between them using the watch buttons. Some of them are more amusing than useful, such as one that shows the time in binary numbers. Some are animations of analog faces. One shows 4:20 written out as "four twenty." 

What's baffling — and a major downside to the Pebble — is that none of the watch faces have the basic indicators we expect from a smart device: whether it's connected and whether it needs charging. You need at least five button presses to reveal the connection status. One press will get you to a battery indicator, but it will only tell you if you battery is low. It doesn't tell you when it will die. 

The battery lasts for about a week, but there's plenty of variability, so I wouldn't be comfortable just setting a reminder to recharge the watch every Monday.The LED street light project accounts for one-third of the targeted 20% carbon footprint reduction for the City. The manufacturer says a full charge takes about two hours, but if you're not keeping track of the time, the watch doesn't help you: It doesn't tell you when the battery is full so you can stop charging.
