MICROCHIP ATTINY25-20SU 8 Bit Microcontroller, Low Power High Performance, ATtiny, 20 MHz, 2 KB, 128 Byte, 8 Pins, SOICThe ATTINY25 20SU is a 8 bit high performance low power Atmel AVR RISC based Microcontroller combines 2kB ISP flash memory, 128B EEPROM, 128B SRAM, 6 general purpose I O lines, 32 general purpose working registers, one 8 bit timer counter with compare modes, one 8 bit high speed timer counter, USI, internal and external Interrupts, 4 channel 10 bit A D converter, programmable watchdog timer with internal oscillator, three software selectable power
The ATTINY25-20SU is a 8-bit high-performance low-power Atmel AVR RISC-based Microcontroller combines 2kB ISP flash memory, 128B EEPROM, 128B SRAM, 6 general purpose I/O lines, 32 general purpose working registers, one 8-bit timer/counter with compare modes, one 8-bit high speed timer/counter, USI, internal and external Interrupts, 4-channel 10-bit A/D converter, programmable watchdog timer with internal oscillator, three software selectable power saving modes and debugWIRE for on-chip debugging. The device achieves a throughput of 20 MIPS at 20MHz and operates between 2.7 to 5.5V. By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching 1 MIPS per MHz, balancing power consumption and processing speed.
- Advanced RISC architecture - 120 powerful instructions, most single clock cycle execution
- Non-volatile program and data memories
- Peripheral features - On-chip analogue comparator
- debugWIRE on-chip debug system
- In-System Programmable via SPI port
- External and internal interrupt sources
- Low power idle, ADC noise reduction and power-down modes
- Enhanced power-on reset circuit
- Programmable brown-out detection circuit
- Internal calibrated oscillator

Decent value for the money.
Size: 6FT*6FT, Color: Grey
Was easy to assemble. Instructions were clear. Tools were supplied. It really needs to be assembled wherever you're going to be putting it as it can come apart easily when moved. The cross bars simply fit into open ended plastic 90 degree female ends. Overall for the money and to just have some division in a room it's a good value.

Garbage
Size: 6FT*6FT, Color: Black
This product is absolute garbage! It literally took all day to put it together and if the air conditioning blows on it the wrong way than the whole thing top over and it falls apart.
It’s not made of quality material and is very flimsy. The only reason I’m not returning it is because it’s too difficult to put together and I don’t wanna spend that much time trying to take it apart. Do not buy this!

Cheap
Size: 6FT*6FT, Color: Black
They serve their purpose as long as you leve them in one place and not moving them around and they're kinda flimsy and some of the velcros are cut too short and can't stay closed
