I was excited to try these lighters out. Although there are several pros to them, the 1 con it has is SO annoying that it wipes away all of the positive things about the lighters and just makes them annoying to use. Here's a breakdown of pros and cons:
Pros: 1. The lighters are lightweight. 2. The ignite button is very easy to push down and is very comfortable to hold down. 3. The flame size adjuster works accurately and effectively. 4. The locking capability is a nice added feature that most standard lighters don't generally have included. 5. The fuel tank seems to be a bit larger and holds a good amount of butane, so you don't have to refill them as frequently. 6. The 3 slits on the front of the lighters give you the ability to view the fuel tank level. 7. The colors of the lighters are bright, cheerful, and aesthetically appealing.
Con: 1. When using the lighters, the flames CONSTANTLY make a very rapid “ticking” sound which in turn also makes the flames CONSTANTLY “dance or flicker” and/or do a slight and very rapid “down and up” motion over and over again directly matching with and in correlation to the rapid “ticking” sound!!! It is VERY ANNOYING and not easy on the eyes after only using for a short while. This is ESPECIALLY bothersome to people such as myself, who suffer from Epilepsy and/or seizures that can be triggered by flashing lights. This occurs on ALL the lighters regardless of the level of butane that each lighter has. I'm disappointed because these are now pretty much unusable for me.
