1) Yes they do work. Have not really measured transformants per microgram
but we usually get at least 10X more than by transformation.
2) Very easy to use. Probably do not need to optimize much at all for
E. coli since the standard conditions work fine.
3) Best value probably depends upon the price and discount your local
sales rep gives you. If you are only going to use it for bacteria be sure
not to buy any special attachments for mammalian cells etc.
