Hi review, kacir,
many thanks for your added info - I appreciate it.
I will take this opportunity to add to m2heikamp's observation about owners pleased with their 302s. But only by a half (to 1.5), for although I have one that is functioning (for the moment) as designed, it's the second one I bought. It was going to be prohibitive for me to return the other, so I gifted it to my sister, who could not afford a device at all, and thought the quality defects (broken internal clock, sd card not being removable) mattered little to her.
My ire is raised through the apallingly unsatisfactory dealings with one supplier (I bought my second elsewhere), and the general lack of support. The words I have used to describe PB as a whole, still apply, and this thread must surely be costing many, many sales of current devices.
But to the dedicated, intelligent, and helpful members of this forum, I am and will remain, extremely grateful.
Cheers,
