BenQ-Siemens EF81 review


If you want a stylish clamshell camera phone look no further

Eye-catching design

Flaky software ; Lack of features

It's rather a case of style over substance, unfortunately

BenQ-Siemens EF81 mobile phone - FIRST LOOK


With a new brand, comes three swanky new phones, but can BenQ-Siemens flagship model, the EF81 deliver the goods? We managed to get a first look at the launch of the new handset in Berlin.

Looks, features, tough

Looks like the RAZR from Motorola

The EF81 is an appealing sequel with a thin metal case and backlit keyboard and, with a 2MP cam and Bluetooth connectivity, it's not to be sniffed at

This is a successor that equals, if not outshines, the original. A bit like The Godfather: Part II…

BenQ-Siemens EF81 3G Phone Review


It was something of a fall from grace considering that way back in 2000, the SL45 was the handset to be seen with, while the SL55 practically invented the slider form in 2003.

The EF81's feature set is in line with its high-flying 3G counterparts but it's the authentic material handiwork that sets it apart.

The keypad design is hardly original, the music player interface can annoy and the camera lens could have sharper focus, but these are hardly major concerns.

BenQ-Siemens EF81 3G Phone


The BenQ-Siemens EF81 is a very desirable & slim 3G mobile phone which comes with a beautiful clamshell opening mechanism. The handset is very small in size & measures 94 x 51 x 15.9 mm which make it very slim & stylish. The handset comes in a titanium...

BenQ Siemens EF81


Prior to the merger with BenQ, Siemens produced some good quality mobile phone handsets, so we were looking forward to seeing some new units. The EF81...

Industrial design, Display, Solid features list

Sluggish interface, Long load times, Poor hinge, Flat keypad, SIM card slot

The EF81 is a decent 3G offering with a solid features set, but users will be frustrated by its slow user interface and sluggish load times.

BenQ-Siemens EF81 review: More than a copy


BenQ-Siemens officially released their new slim clamshell EF81 on the market. A lot has been said about it resembling Motorola V3x. Indeed, the new BenQ-Siemens does look like a RAZR and many people would definitely take it for a V3x by mistake when...

The EF81 folding mobile with its ultra-slim form and high-class magnesium casing is an instant eye-catcher. Moreover, the new flagship device of the young BenQ-Siemens brand provides full UMTS functionality and boasts two large color displays and a...
