Q & As

Rated 4.3 out of 5 by 30 reviewers.
Rated 3 out of 5 by Excellent apart from tone The tone is usually good for music but less so for talking. It really needs a tone control 04 August 2015
Rated 5 out of 5 by Excellent product I bought this Roberts DAB radio to replace a broken Pure one that was a few years old. The Roberts radio is far superior, from the touch of the buttons and functions, to the sound quality. I'm very pleased with it and would definitely recommend to friends. 28 July 2015
Rated 1 out of 5 by Little or no reception I purchased this last weekend and chose this model as I have a smaller Roberts version for outdoor use. Tuning the new radio was exactly the same as my current one but however hard I tried, I could not obtain a permanent connection on the DAB to any of the stations. Using the FM was almost as bad with the station coming in and out. Even relocating to other parts of the house did not improve the situation. Am very disappointed and now have the inconvenience of returning the item. In the meantime, I have ordered the Ruark version II which I hope will be a better product. 04 June 2015
Rated 5 out of 5 by Compact DAB Radio This is the larger model of the Roberts radio I previously bought. Having twice the output it gives great sound while still relatively compact. What I found useful, and my reason for buying Roberts again, is the 'favourite button' which gets you back to where you want to be with just one press. You can easily find other stations after presetting them (an easy operation) by turning the dial and depressing it. I would recommend it for these reasons. 16 April 2015
Rated 4 out of 5 by Roberts Radio I purchased this because I had had a bad experience with a previous Roberts radio developing a problem shortly after the one year guarantee had expired. I was advised that John Lewis did a 2 year rather a 1 year warranty on Roberts products so that was the deciding factor. The radio is what I need in terms of a portable and has the added advantage of a built-in battery charger (the purchaser supplies their own batteries). One snag is that lacks a proper carry handle but it is light enough to grip as a unit. 03 March 2015
Rated 1 out of 5 by Dreadful sound quality Reading the reviews I unfortunately purchased this DAB radio as a Christmas present. The sound quality is truly awful, the speakers distort/vibrate even at low volume levels, thought it may be a signal problem but we live in a strong signal area. Suffice to say its being returned to John Lewis. 16 January 2015
Rated 5 out of 5 by Roberts Duologic Radio I am impressed with the John Lewis high standard of service! - Second to None. As with the click & collect . The Radio arrived the very next day - Actually before the alloted time . The staff were very friendly and helpfull. And what I like about this Duologic radio is - with the built in charger I never need to buy battaries again and it sounds great! why aren't all radio's made to this standard? Good on you John Lewis! & good on you Roberts Radio! for your eco friendly - good for the enviroment Range of Radio's. 06 January 2015
Rated 5 out of 5 by Excellent sound Really good sound from such a small enclosure: our previous DAB Roberts radio was nice but with one speaker ( apparently with DAB this makes a difference) hardly loud enough to hear against any background noise- this has 2 speakers and pumps out a more than healthy volume with a lively, clear, natural and rich quality. We listen mainly to Radio 3 and 4. The controls are easy to understand, unlike many and nice to use, the display clear, all in a good quality and neat, elegantly designed package. We currently (!) run it off the mains and cannot vouch for the battery performance. 04 December 2014
