BG115520162 Looks like they're painted on, but I don't have enough magnification here to say that conclusively. There is a punch hole every 5 mm. It's very nicely made considering what I paid and it still looks brand-new after being out in the rain all winter.

BG115520162 I haven't officially used mine yet but it works with a typical western residential power line (220v). I intend to use mine to boil water for purging solvent-based plant extractions but we're just now exiting the testing stage. This heater is much larger than many similar devices on the market. I was able to find a XL lasagna pan at Walmart that's 4 inches deep, more than enough to completely submerge the heater in water. (The manufacturer recommends using a bucket of water, fwiw.) This heater is larger, thicker, built better and able to boil more water than comparable devices. It is intended for use in 220V systems. I usually try to use a power strip with its own switch so that power to the unit can be cut quickly in the event of a spill, etc. Hope this helps. Best of luck to you. snit

BG115520162 I do not believe this drone is waterproof. It also lacks the ability to drop items from the air. Both of these features might be available on more expensive drones. This is an entry-level, sub-$100 drone best used by pilots who are newcomers to drone flying. The features you seek will not be found here.
