Work perfectly with my Optoma HD25-LV
on 1 June 2014
I recently bought a 3D projector (a counterfeit lamp destroyed the previous non-3D projector I had).
I've been underwhelmed by 3D TVs I've seen but wanted to see what it was like on a big screen.
The Optoma RF 3D kit is about £90 (with one pair of glasses) and then extra glasses are about £80 a pair.
For £72 I get 4 pairs of these - it's only a bit of fun - so these I bought.
Well, it's not 'a bit of fun' - it's awesome!
My screen is about 10 feet on the diagonal and is viewed from about 14 feet away.
3D gives another dimension to watching movies (pun intended).
Everyone to whom I've 'demoed' this set-up has been totally blown away by it. 3D cynics (like me) have been totally won over.
I should warn that the HD25-LV is a 'hi-brite' projector so might do rather better than some other projectors.
These glasses work flawlessly.
A single charge lasts for .... Well, I really don't know! I've re-charged them after maybe 6 or 7 hours use simply because I thought it might be a good idea.
Yes, they'll lose synch if you're not looking at the movie - but look back and they'll re-synch in the blink of an eye.
It's better to think of the 'on/off' button as the 'something's not right' button. Let me explain:
You want to watch a movie you press the button on the glasses - they turn on. If you want to turn them off - I don't think you can - you just let them go to sleep when they're not being triggered by a 3D movie. This 'I can't turn them off' isn't a problem; as explained earlier one charge lasts for a long, long, long time.
Where the magic button is important is when viewing a movie. I find that frequently (more often than not) the left and right eye views are switched. What you should be seeing with your left eye you see with your right and, obviously, vice versa. Click the button once and it switches the eyes over. You can work out if it needs switching by closing alternate eyes - but it's not worth doing that. When you start viewing, click the button and choose which is the most comfortable, clearest view.
If you wear prescription glasses it's no problem; these easily fit over existing glasses(unless you're Edna Everage).
The only slight criticism is how comfortable they are over lengthy viewing periods. They're not hugely uncomfortable but they are 'one size fits all'. The great thing is that at less than £20 a pair you don't panic about making a few changes. My wife complained the arms were too long and hit the chair back when she settled in to watch a movie. No problem, I snipped an inch off the arms, smoothed off the ends and job done - she now has her own bespoke pair and is perfectly happy.
Very highly recommended - you really can't go wrong at this price.
