    A great replacement for my old armband
  

*by H***R on Reviewed in the United Kingdom on 1 February 2013*

My husband bought me a HTC Desire phone with a 16gb memory card and Otterbox Defender phone cover. It was gjust the thing for taking with me to the gym or out for a run, but I had just one problem - my armband was too small to take the phone (it was for a Samsung YP-Q2 mp3 player).As it was close to Christmas, I dropped a few hints to my husband that I needed a new armband for my phone, so he got me this as part of my pressie.I have to say this armband is ideal. It is made to a very high quality. The phone fits snugly inside, even with the cover on, so no fear of it jumping out when I'm running. The headphone cable loop is a good idea as well. My cable doesnt get snagged anymore (I don't know how many pairs of headphones have broken on me because of cable snagging). My husband said he had read reviews where people had said the armband itself was too short and an extension band was required, but mine fitted no problem. It is a little bit more expensive than other similar armbands but it gives me peace of mind that I can still keep my phone in its protective cover while using it, so the extra couple of pounds was well worth it for that.I am now happily using it for all my activities. This is an armband I would highly recommend for any users of Otterbox phone covers.

    Does the job...
  

*by A***1 on Reviewed in the United Kingdom on 5 June 2013*

This armband takes my iPhone without removing the Otterbox case, thereby saving a lot of hassle. Its a tight fit and takes a bit of persuasion to get the phone in - but that makes it secure. Quality feel to the cut and stitching. The fit on the arm is secure and comfortable through a vigorous cycle ride and showed no sign of slipping or loosening of the velcro (I forget I was wearing!). Trying to use the touch screen through the plastic cover is a bit hit and miss - but the basic function of answering or making a call is fine. I can see this will be a part of my standard cycling kit till I upgrade to a phone that doesn't fit.

    Fits a treat....!
  

*by V***D on Reviewed in the United Kingdom on 26 January 2012*

Chose this after a friend showed me the Tunebelt armband he'd got for his Desire HD. I wanted one that would take my Sensation XE with a 'Casemate Barely There' protective case on it. When I saw this advertised as being able to take a Phone complete with an Otterbox Defender case on, I knew this was worth a try. (Otterbox Defender cases are good but reasonably bulky).When it came I was suitably pleased, both with the quality and the fit, Perfect.... not too tight, but able to hold the SXE securely with the case on. The plastic screen cover still allows access to the phone touch screen functions. It even has a velcro strap to hold your earphone spare cable tidy. Users should be aware that the armband length is not very generous, those with big biceps or want to use it over a coat sleeve will need to buy the extender strap that is offered on various sites, inc Amazon. Overall though I'm quite happy with my purchase, but haven't put it to any real test. PS this does not appear to be a waterproof product, just water-resistant (light shower).Not the cheapest on the market, but it does what I need it to do....
