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...

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


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 mobile phone - FIRST LOOK - Pocket-lint


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

Looks, features, tough

Looks like the RAZR from Motorola

Three years ago, Siemens Mobile was on at the top of its game with models such as the sliding SL55 (a predecessor of sorts to the Samsung D500 and D600 models) but towards the end of its life the company managed to lose its way. Even Clemens Joos, the...

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


Siemens Mobile division, over the past half-year of existence, has developed and released a number of products, at that the main aim, in order to maintain fading away sales, was copying a successful opponent. Though for this role, for some reasons the...

The battery's cover is just one more occasion to make certain that all good ideas are worth their weight in gold the design precisely copies the original RAZR solution, and it's good to see when there are some standards which are observed. The only...

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...
