QI wireless chargers

My next mobile phone (currently languishing in a Parcelfarce depot somewhere in England) supports wireless charging using the QI standard. Not the reason for purchase but would be a shame to not dabble in using it. Have googled the various charger offerings and nothing seems to stand out from the pack as being the one to buy. Most have polarised reviews of 5 stars as it does what it says on the box and 1 star where it doesn't.

So the question is has anyone else dabbled in QI and would be prepared to recommend a charger?

Regards,

Willy.
