Things I liked:Small and compact. Easy for storage. Must have in order to tune your gun. Things I would have changed:Make it usable indoors. Works great outdoor, but inside, it wont read at all. Will need to purchase separated lighting from PA in order to use inside. What others should know:Will not read indoors with ceiling lights. They will effect the senors, giving error reading. Must purchase lighting equipment from PA (about $46 extra), in order to used indoor.
Things I liked:Price and accuracy. Used them in my marauder .177 they shoot great. $3 cheaper than the JBS. Saving $3 per tin is pretty nice. Things I would have changed:nothing. What others should know:The skirt can easily deform, so handle with care and they should be fine.
