My Bushlite is still ticking along nicely after years of use. I bought a spare glass when I got it, assuming that a breakage was likely, but that has remained wrapped and unused. Price's Household Candles work very nicely in it and cost less than a pound for half a dozen, unlike the the very expensive (but slightly longer lasting) candles for the likes of the Uco. You can also break dining table candles in half and use those, but the Price's fit perfectly.
The spring does occasionally get gummed up. A quick scrape with a knife or stick clears it.
There's a reflector available for the Bushlite: it works well but you could get much the same effect with some foil. The "official" carrying pouch is a bit poor, being rather a tight fit and not padded. Make your own for a better result.
Overall I'd recommend the Bushlite. Nice comforting glow (not as much light as from gas or battery powered lanterns, of course) and generally foolproof. For several years I used it at home as a bedside lamp, too.
Attleborough Accessories still seem to be stocking it (I bought it from an earlier UK distributor who apparently went out of business) but prices are higher than I remember.
