I liked the look of that Lomo thingy so ordered one and it came this morning. (£15 + £2.99 delivery)
Overall impression that it’s good, did a ride up the street a bit.
Some points:
It’s going to be totally waterproof I would say
I wonder how long the rubber band will last, and they should have sent a spare (meaning it would have been better if they did)
It’s a very stiff piece of rubber, and once it’s on it is very secure
The case itself: holds a phone but not room for much else but I guess that’s alright. The phone doesn’t move inside it
The back of the case is padded, so it feels that even riding over rocks the phone will be ok... time will tell.
But the moving plastic bits mentioned below may suffer a bit from the forces from bumping over rocks...
If or WHEN you fall off the case and phone and gubbins will not catch any or much harm unless a tree falls on you - ouch
The Perspex outer of the phone - wonder how long that will last ?
The back of the blue case has a plastic piece, secured by 3 sturdy ‘inserts’, which easily clips into the holder on the stem, and it removes easily but also locks in place.
The holder (now on the stem secured by the above mentioned rubber band) is a point of weakness. It allows 3 different positions, flat, tilted up, tilted up a bit more... wonder how long all those plastic moving parts will last?
Finally got it fitted - need strong fingers depending on how thick your stem is. The blue case does waddle quite a bit, so I was thinking should I apply a bit of araldite to ‘tighten’ it up a bit OR phone them to see what they say...
However riding it up the street it didn’t seem to be a problem.
And I could still operate the phone as pressing the ‘perspex’ case does get through to the phone..
I got Aneta to phone me as I was riding and everything was fine.
So far so good...
The reason I like the idea so much is that when I’m out I very often have to stop, get the phone out of my pocket just to read the map (I use Memory Map

), and because more often than not it’s peeing down I have to take the phone out of it’s little freezer bag...wipe it with a finger because it’s now wet...
I have to do this because following the line on the Garmin is hit and miss.... you find out you’ve gone wrong when you’re off course by quite a few metres..
With Memory-Map (and it works in airplane mode to save battery) your position is a cross hair and the good thing is that there is a long red line with an arrow at the end, which indicates your direction...very useful.
I also have the phone in low power mode, so it goes blank after about 10 seconds.... however if I want it on so I can see where I am I’ve set up (which you can do with an iPhone) as part of the ‘one swipe up’ from the bottom of the screen, an icon for low power mode to easily turn it on/off... and this ‘swipe up’ works through the Perspex, even in the rain.
So it’s looking good - praps I won’t get lost as much... (if anybody at Gsrmin was interested you would think they would develop a gps specific with a good resolution screen, without eating the batteries too much)
