Ex Input:
These notepads are difficult to write on with a Fisher Space Pen. It does work, but the writing is rather splotchy. Works great with gel ink (but may smear), and is alright with regular ballpoints. It repels water on the surface, but the edges allow water to seep in, so underwater writing may not be a good idea.

I've had my lights for about 2 weeks now and they are great until they weren't... first couple of days super bright! as of today I've had to replace with my original bulbs due to the light being produced which is almost nonexistent. I've check all connections still nothing. Not sure if I just received a faulty set or what. I've messaged the seller about the issue awaiting a response. I will update my review once I receive a resolution.

Great game but the low energy/having to buy energy for moves dims this gaming experience. This game has Great graphics and interesting plot and execution but the constant energy low after a few moves killed this for me and really turned me off.
