It comes in handy for videoing swimmers during practice. The images from the projector can go as large as 50 inches before they get too grainy for use. I find it works well for groups, or for swimmers whose vision is poor.
The biggest trick is to find a darker area, in/around the pool deck to make it useful. At our pool, we have a darkened entry way with a big bulletin board that works perfect as a projection area.
The kids like the fact that they don't have to look over my should to get a view of their strokes and technique. It even has a fairly good set of speakers on it.
I have used it to project Netflix and YouTube videos, and it can also be used to project presentations and photo albums.
The drawbacks to the unit are:
- it is a little big to use as a permanent iPhone case. I usually just slide my phone in as needed.
- it does not have an adjustable stand. If you are using it for presentations, or as a stationary projector, you may need to prop it up on some books to make it the right height for your "screen"
- the $229 price tag is a little hefty. I definitely had to do some soul searching before I bought it.
All in all, I think it is a worthy purchase...at least for me.
