Today we revisit those Bluetooth bracelets that offer the convenience of never missing a cellphone call by giving a gentle, vibrating buzz on the wrist informing us about an incoming call.

Missing a phone call is sometimes not a big issue but at times it can have an impact on our love life, work life or whatever else is important and depends on that one important call.

ThinkGeek has their BlueAlert bracelet on the market for a while and Korean based MOVON has one in their current product portfolio the MB80 which not only alerts via vibration but can be used as a handsfree device bridging the gab between you and the cellphone.

According AVING USA, MOVON will introduce at the currently running CeBit in Germany the scaled down version called MB20 which will give a vibration on the wrist, indicating an incoming call. It does not look overly stylish, is supposed to come in three colors: black, white and brown and will be rechargeable via a USB port.

A simple, no frill design which will become useful while being around noisy areas like busy shopping streets and the cellphone is resting deep inside pockets.

Nathan‘s Human Propulsion Laboratories dedicate themselves and their products for the active sport community offering gear to make cycling, running and the like more enjoyable and save.

In the later category, the safety gear, Nathan offers LED Vests (which look a bit like safety gear for street worker) but more practical, functional and better looking wrist and ankle bands that can be switched on when the sun is down for the late evening run or bike tour.

These bands are visible up to one mile and re replaceable coin cell batteries give light up to 150 hours, so you can go on a very long run.

The wrist and ankle bands have a zippered pocket for small essentials, are made of lightweight fabric with Velcro closure.

Available here for a more than modest price of $9.49, a bargain compared to the benefit and disaster it can help preventing by making especially runner more visible during night.

If you are a professional talker on a cell-phone or walkie-talkie you might be interested into the Wrist Band Portable Battery from Chinavasion.

Although this power wristband might not be something a fashionista want’s to be seen with it might be handy for above mentioned professionals where performance (in this case up to 3 hours additional cellphone use) has higher priority as the looks.

Chinavasion offers wholesale orders but accepts single unit orders as well for $24.84

For that price one gets 7 types of power connectors for the most common portable devices including essential like PSP and DS (so it might be as well useful for the gamers) and the iPod folks can top up the charge as the wristband has a Mini-USB as output port.

A line of 4 LEDs visualize the power load of the wristband which takes 5 hours to recharge via USB.

If all those charging options blow your mind and you put aside your fashion consciousness you better head over to get one.

Missing a call on your cell phone is annoying to say the least and can be disastrous in other cases. I don’t know anyone who did not have such unpleasant ‘missed that call’ experiences. The problem usually happens if you keep your phone in a pocket or bag. Not everyone likes to hold a cell phone in hands all time or have it tangling around the neck.

As many people as I know having the ‘missed call syndrome’ as many design concepts exist that promise to solve this issue by integrating visual incoming call alerts into easy to see items like clothing or bags. Only – not many of those great ideas did make it into the market yet.

It’s again up to ThinkGeek, famous for cross-over fashion-to-function products, to save the cell phone world by launching the ‘BluAlert Bluetooth Bracelet’.

The BluAlert bracelet uses Bluetooth technology to buzz discretely on your wrist when your phone rings. Even in the loudest room or the most boisterous dance-floor, you won’t miss it when BlueAlert goes off.

As added bonus, the BluAlert acts like a security device, once paired with your phone it will start buzzing when you are more than 5 meter separated from your phone.

Impressive also the standby time of 100 hours by a charging time of only 3 hours.

The BluAlert bracelet might not be the most fashionable wrist jewelry but it promises to do a great job in keeping the communication lines open all times.  Depending on the value you attach to the option to never miss a call again (and maybe never lose your cell phone again) you might actually be willing to make a fashion compromise and spend $49.99 to get your BluAlert.
