25cm Arc Bluetooth Square Wave PCB Musical Tesla Coil Scientific Experiment Toy- US PlugFeatures:
.Desktop integrated mini solid-state Tesla coil finished product, the primary and secondary are made of PCB. It is a change from the traditional solenoid secondary Tesla coil, which is highly integrated and more clean and safe.
.The Tesla coil power supply is only 48-54V DC, and the low-voltage power supply ensures safety, and the effect is stronger than most desktop-grade commercial half-bridge Tesla coils on the market. The 2M high frequency sub-level, there is no pain even if you touch the arc with your hands.
.The 2 in 1 Tesla coil has both a toroidal coil and a coil head integrated with 6 discharge needles. Plug in the power supply and you can experience the charm of lightning in the palm.
.Bluetooth connection can play square wave music, increasing its playability. At low frequencies, you can freely play the arc between your palms. The frequency of the music mode is higher. When the arc is concentrated at one point, there will be a burning sensation.
.The power supply is a DC power adapter, no need to be grounded, it is more stable, the heat sink has a temperature control switch, the power supply has over-current protection, the pulse width of the music mode is limited, and multiple protections. There is no fan to dissipate heat (because the heat is very low), do not run at maximum power for too long, so as to avoid the temperature control protection is too fast.
.Instructions for Use: Switch down to fixed frequency mode, the knob to adjust the arc frequency and size, pause in the middle of the switch, switch up to music mode, use the audio cable to link the phone to the maximum playback, the knob can adjust the size, the right knob Control the size of the arc and twist the clockwise pointer. The left knob controls the fixed frequency frequency, and clockwise speeds up the arc spray frequency. It is best not to open the maximum arc in music mode all the time, so as to avoid the temperature control protection is too fast. If the arc in the music mode is turned to the maximum and sometimes discontinuous, this is caused by excessive power supply protection. At this time, a small arc should be opened appropriately.
.Very good science and intelligence gifts.

Pretty good.
Color: Natural Wood, Size: 6 Panel
Wrong color. Uniform color instead of 2 toned as depicted in the picture. But well made.

Exactly what I was looking for.
Color: Brown, Size: 3 Panel, Color: Brown, Size: 3 Panel
Although other reviews found this item was too lightweight and flimsy, frankly it was exactly what I was looking for. I needed to partition my workspace off from the rest of the room and I wanted something that I could easily attach to the back of an unfinished bookcase as part of creating a private space. It was perfect. Lightweight easy to handle and I didn't mind putting some nails through it. Great price point for what I needed.

Made cheaply.
Color: White, Size: 3 Panel
Seems fairly sturdy ( 3 panel white) but made with extremely cheap materials that will not last. The cheap materials are very noticeable with the white screen. No assembly needed. Would not but again.

Beautiful brown privacy screen!
Color: Brown, Size: 3 Panel, Color: Brown, Size: 3 Panel
Why did you pick this product vs others?:
The measurements were perfect for what I was looking for. The length and width are the same as my rattan raised garden bed which I have placed in front of the screen on the deck. This secures the screen so there is no issue of weather conditions. I have been looking for weeks for a privacy screen at every possible product and combination. and almost gave up when I noticed the measurements of the screen would fit behind my raised bed! Now I am going to plant some flowers in it. This is a terrific buy for me. i am so happy!
Looks great:
The perfect size, color, and design match my brown deck rattan furniture.
Ease of assembly:
No assembly which is nice in this hot weather!
Room divider:
It provides much needed privacy
