Summary: This is a decent presentation remotes. The only issue I have experienced so far is that the battery cover falls of all the time. Several dozen times per hour long presentation. This occurs so excessively at times that it has become distracting during some classes. This condition would be easily remedied with a proper application of duck tape, however I feel that is an unnecessary repair for a $60 remote. Despite that design flaw the remote works well otherwise.
Summary: This remote solved my Macbook Pro Retina remote problem immediately upon it's arrival. Within three minutes of opening the packaging, I was up and running without having to read any directions or install any software. It took me a few moments to learn how to manipulate the cursor on the screen, but after I did, all was well with the world.
Summary: Works well for us. Preacher uses this remote to advance his own slides during the sermon. We keep the receiver in the line of sight but sometimes the speaker doesn't hold the remote where the line of sight is unobstructed, yet it still works anyway (receiver is about 50' away). Batteries seem to last a good long time, but we do turn it off after each use. It's been about 2 months and first set of batteries are still in it.
Summary: So these are the Pros: -It has a good feel to your hand - Driver installation is a breeze -It has all the necessary buttons to avoid having run to your pc all the time -the mouse control is very manageable -it has a durable appearance Cons -the laser button is awkwardly placed (it should be at the top and not middle) -the battery cover is very loose ( I used a piece of folded paper over the battery to add some thickness, so the cover would be firmly attached) I hope...
Summary: I typically use a desktop USB extension (several available from Newegg) to locate the receiver in a line-of-sight location away from other equipment, usually placed on top of a podium or table.
Pros: Simple setup in Windows7, easy to use. I've presented in large and small rooms using many different devices and this remote is my favorite.
Cons: Range will depend on RF noise in the vicinity. Other 2.4Ghz devices in use may cause range issues (like some cordless phones.)
Summary: Owned a few remotes over the years, always seemed to be a problem with Mac OS X (whether the remote didn't work at all OR the remote worked only sporadically, losing connection from the remote to my laptop). For all of you Mac users out there, this remote works perfectly with Mac OS X 10.8.4 (most current version at the time I write this). THe range of this remote is terrific, 30-40 ft (I have not tested it at further distances) is not a problem.
