How do I clear the memory once it is full? I have uploaded the data to my phone already.

Once downloaded there is a "dustbin" symbol in the top right of your phone screen to delete the data from the Oximeter

Can results be put on laptop? I have no mobile phone. Also can it be used as a one off for quick oxygen test?

No, as per the information in the description, it's only compatible with Android or iPhone. As for a "quick oxygen test" why would you do that? You would want a fair bit of data over time to average out the readings, because your SPO2 does fluctuate. A quick reading might give unnecessary concern, if it's dipped to say 92% briefly but gone back up to say 98% - this info was relayed to me by NHS 111. You can just as easily buy a cheap oximeter and get the readings from the actual device then write them down. Always work with your healthcare professional. Hope this helps.

How well does this attach to your finger during sleep?

It has rubber inside and fits and stays on finger during sleep. It stays very well and doesn't hurt.

Only getting 6 hours recording on one set of batteries, 8 hours on another set. Says 24 hr Continuous recording? I must have a faulty unit.

I managed to get three 8 hour recordings from one set of batteries.
