It is 19x11x7cm, weight is around 700grams, the grey sides are rubberised as is the base of the seven section rod aerial that extends 58cm from the top of the unit. The back has 3.5mm connectors for line in and earbuds. There is also an input for the mains adapter. Everything else is controlled by five small rubberised buttons and below that two larger rubberised twist knobs are below back. Above these knobs is a 5.7x1.

Slightly blocky in shape and unusual in layout for a DAB/FM radio and add the hand crank on the rear it is unusual. It is 20x12x8cm and weights1060grams. Remember the extra weight of the built in Ni-MH battery and the alternator. The face has a single 8cm round speaker housing, eight silvered well labelled buttons, a grey volume knob and a double tuning knob the outer one for FM and the inner one for DAB.

It was certainly not what I expected when I requested a review unit.  Unlike the other voice recorders, this LINDY Wireless Voice Recorder requires to be connected to a computer running appropriate software before you gain access to its functionality which is rather restrictive when compared to some other voice recording devices.

They are a pair of cone shaped speakers that need power but not necessarily any connection as they can operate by Bluetooth. However they can be connected conventionally. They are 15cm long, 13cm across and stand 16cm high. Each has it's own power supply and lead so they do not even need to be in the same room. The signal is transmitted from one to the other so if setup in a stereo configuration that is what you hear. Each speaker weights around 1100grams.

The DualIt Lite DAB radio is 22x16x8cm, it can be run either from batteries or mains. It has a 66cm six piece rod aerial that folds out from an indentation in the top that looks exactly like the hole that you would insert bread in. The back has a very tight entry point for batteries and if you use rechargeables there is flip a switch in the compartment it can recharge them in situ while still listening from the mains.

Intended for use in the car (the only charger provided is the one for a cigar lighter) a standard mini USB to USB will charge it in less than four hours. I always test it on trains and or buses as well as in a car. Unless you are a passenger you cannot really look at the screen of the unit and while travelling in a bus or train gives you that opportunity.

The Tangent Cinque DAB radio is 23x21x12.5cm, as stated mine was shiny black that will normally show all the fingermarks but once in place you really only need to touch it to insert or remove CD's and as that is a slot loader not really even then. It looks magnificent with the black mirror finish. The rear has the various connections and an eight piece (67cm) rod aerial.

The box contains a pair of Freetalkie XFD-008 wrist watches. They are chunky and you need to wear one for awhile before you get used to it. Yes it does tell the time but the main point is that the watch is a walkie talkie. After a couple of days of wear you get to the bulk. The weight of each unit is 80grams so it's not that heavy just bulky. The stated range is 'about 1.

The Polaroid frame itself is black and 25x18x3.5cm. The screen itself is 15.5x8.5cm this gives the 7inch diagonal measurement. Under the screen is an LCD display 15.5x1.5cm that displays indoor temperature and humidity as well as outdoor temperature and the likely weather. I found the latter was not that believable but the outdoor temperature was correct as this was sent by the provided wireless sensor that you place somewhere outside.

It is 20.5x16.5x2.2cm. The unit I had was white with a couple of blue horizontal stripes across the front. The centre part of the front is the display screen and this is 13x8.5cm and this gives by my mathematics a diagonal measurement of 6.2inches so I am not sure where the stated 7inches comes from. In another of life's situations if you told a lady to expect 7inches and you delivered 6.2inches she would almost certainly notice the difference.

It is a maximum of 25x12x6cm, mine was white, but they also do black. The rear has a six section 55cm rod aerial, jack sockets for output to stereo speakers. A 3.5mm earbud socket and input for the power socket, the only other socket is on the right side 'Mport' that allows inputs from other sources such as an MP3 player. The centre of the front has a 6.5x2cm three line display, white on black. When in standby this will show time and date.

In the box is a lead to go to your cigar lighter to provide the power. A rather flimsy aerial to attach to the inside of the windscreen, a bracket (much like those for Sat Nav systems) to fit the unit into, an optional line out lead and of course the DAB radio module. It is 12x7x2.5cm. When you first apply power it tunes so you need to have connected the aerial first.

Jabra BT3030 As the box states 'Music and Talk meets the streets'. This is far more than a basic answer/call unit it can of course do that but it also allows you to increase/decrease volume, move back/forward tracks as well as star and stop. Of course there is also a phone button. The whole thing is a 5.5x3.5x1cm 'dog tag' style unit that comes on a chain to fit round your neck.

The FK-760 - sold by Gizoo details at the end - is available according to the box in Black or Silver or Red I was sent the more normal Black. However for lounge use the other colours might get a look in. This is the same model I looked at first close to 18 months ago. Once I reviewed it several people said that the one they were selling was different well it's now back in stock and indeed at less money.

Each of the two plugs is 10x7x4cm when inserted into a 13amp plug socket. The actual power socket is at the bottom of the unit so you could have problems if there is limited clearance above the plug. In fact you need to add 3cm to the 10cm height for the supplied 1.8metre Ethernet cable. So you actually need 9cm of clearance above the socket.

Parrot Hands-free Speakerphone This is designed to fit over a sun visor enabling almost any Bluetooth phone to be used hands free. The unit is 10.5x6x2.5 and is two tone shiny black plastic and matt black rubberised for the edges and side of the end knob.

Click image to enlarge First the size it's 11x8.5x2cm and although I have used it on a bus there is no pedestrian mode so only designed for in car use and of course all the required fittings are supplied. However the battery gives enough power for around two hours use away from the cars cigar lighter power.

My first question then is why is it called a DigiWalker? However lets assume there is a reason this seems to me to be a rather good unit. Trying to assume the role of someone who has never had a similar unit could I insert it in my car by using the 13 pages in the getting started guide that are in English, answer yes. Could I plan a simple route answer yes.

Recently though BlueTooth - the short range wireless standard - has come to the rescue with a number of solutions. The simplest of course is to use a . These often not geared to car use - and of course you have the problem of looking like a berk. BlueTooth headset The alternative is a BlueTooth speaker phone. There are a few on the market and here I'm reviewing the 'SuperTooth Voice' product.
