It has a manual key override, no need to cut off fingers, just get the damn key reprogram it to your print. And you have to specify right or left hand since the scanner is on one side not both.

Do you have a safe or anything that requires a fingerprint scan? If so have you ever noticed that if your finger isn't just right on the pad it won't read properly.
I personally think it's a dumb idea and I doubt many people will purchase the kit.
iPhone fingerprint scanner works pretty good. They get better as they go along. Manual key override requires the key, the user is assumed to have a means to secure the key away from the weapon. Depends on your personal situation. Do you lock your car door? How about the door to your place of business? I don't have a problem with easily removed locks, people use em or don't, free country. That said if a kid drowns in you pool and you did not have a kid proof fence... expect to be sued and loose. As these gun locks become more pervasive expect to be sued if a kid shoots someone or himself with your unlocked gun.
Door locks and not impenetrable.
I addressed your key override key remark already. If I person can steal your gun, he can also steal the override key.
Are you sure you want to compare children drowning in pools to those dying by guns?
1. Fact: Twice as many children are killed playing football in school than are murdered by guns. That's right. Despite what media coverage might seem to indicate, there are more deaths related to high school football than guns. In a recent three year period, twice as many football players died from hits to the head, heat stroke, etc. (45), as compared with students who were murdered by firearms (22) during that same time period.[1]
2. Fact: More children will die in a car, drown in a pool, or choke on food than they will by firearms. As seen by the chart on the previous page, children are at a 2,000 percent greater risk from the car in their driveway, than they are by the gun in their parents' closet. Children are almost 7 times more likely to drown than to be shot, and they are 130 percent more likely to die from choking on their dinner.[2]
3. Fact: Accidental gun deaths among children have declined by over 50 % in 25 years, even though the population (and the gun stock) has continued to increase. [3]
4. Fact: Despite the low number of gun accidents among children, most of these fatalities are not truly "accidents." According to Dr. Gary Kleck, many such accidents are misnamed -- those "accidents" actually resulting from either suicides or extreme cases of child abuse.[4] Dr. Kleck also notes that, "Accidental shooters were significantly more likely to have been arrested, arrested for a violent act, arrested in connection with alcohol, involved in highway crashes, given traffic citations, and to have had their driver's license suspended or revoked."[5]
