User questions & answers

Question:	will it work on an iMac
Answer:	I think it does, but I would not count on it being very good with a cheaper safe. This safe is very “cost effective” so it’s probably not a fantastic fire rating.
Question:	Does this read the panasonic p2 card
Answer:	To some degree I’m sure it is, as most safes are. The more expensive typically means a better fire rating. This safe is not very expensive.
Question:	is it Reader/Writer or just reader device ?thanks
Answer:	It says that it is, fortunately I haven’t had the opportunity to test it. Most safes are, but the level of fire safety seems to increase with the price. More expensive, more safe.
Question:	Can this read a card slow enough for my grandmas birthday
Answer:	I am not sure we’re you can get parts mine did not have a set button on the bottom safe so I asked for it to be replaced
