First off, let's be clear: the WRW-206 is a metronome and *not a drum machine*, so the view here is from that perspective. This unit is competing as a low-cost alternative to the Dr Beat 90 ($160) and the Tama RW200 ($90), which are drummer's metronomes and for the money it delivers a great value.Quality: I'm always wary of cheap Chinese knock-offs, but I have to say that the WRW-206 has very good build quality, feels solid in your hand, works well as a metronome (caveats below) and delivers some features the more expensive units don't have. The tempo dial turns smoothly with detentes that click nicely. The sliders and buttons are pretty solid as well. Also, this thing is much bigger than the picture suggests -- similar outline to the other 2 units, but thicker by about 50%. It includes an integrated stand, a threaded hole for bolting to a stand (1/4-24 Thread) and a nice "velvet-ish" slip case.My usage: For my purposes this is a great unit. I play for Irish dance competitions which requires up to 8 hours of playing. Strict tempo is required, so I have a metronome going in my headphones the whole time and have to changes tempo and time signatures frequently between competitions. The unit has 50 memory presets and you can change between stored patterns with the big selector wheel or a 2 button foot switch (not included, but readily available), so it's easy to switch once you've programmed your patterns.Sound: The drum sounds are great for my purposes (listening through headphones), but remind me of an 80's drum synth -- not realistic but pleasant enough in their own way. Since the piercing chirp of most electronic metronomes would send me over brink of sanity after a few hours, I was looking for something drum-like and this fits the bill. Keep in mind, the purpose of a metronome is to keep the musician on the beat, not to stand in for a drummer.The metronome sound through headphones is clean. In addition, the instrument input and volume control allows you to listen to a mix of metronome/instrument headphones, which is nice. The little speaker is not great and I'd only use it in a pinch, but since my primary use is headphones, I don't care.Learning curve: This is my biggest complaint. Programming this thing isn't intuitive and the instructions are pretty sparse (the info is there but I had to experiment to understand what they meant by each term). I spent a couple of hours patiently playing with the unit, deciphering the instructions and eventually figured out most of what I wanted to do.The good news is, once you have your patterns programmed, it's easy to use in a live situation: turn it on, select the program with the wheel or footswitch and hit start.Pros:- great price at $54 with Prime shipping (30-50% the cost of the 2 main drummer metronomes)- good build quality, OK variety of sounds (for a metronome),- good sound quality through headphones- 2 separate foot switch inputs: one for start/stop and another for program select- capable of complex patterns that can be stored in the 50 memory preset slots- headphone jack with volume control- instrument input with its own volume control (plays through speaker making this a really crappy amp!!)- threaded insert for mounting to a stand (1/4-24 thread) and wire "kickstand" for tabletop use- AC input to avoid relying on batteries (AC adapter not included).Cons:- poor instructions and unit is a little quirky, expect to invest some time learning to use it, otherwise you'll curse it- uses 9V battery (would prefer AA), no AC adapter included- speaker is tiny and tinny- drum sounds not very realistic (although they're effective for keeping you on the beat without torturing your ears like many electronic metronomes)

Terrible manual. Terrible sounds. A drum machine would be a much better option. No videos on "youtube" in english so all you can do is watch the instruction in Russian and guess what they are saying.

A little cheap feeling and not loud enough to use in an outdoor setting. Does do a good job subdividing.
