We bought a new Keurig K-Duo and needed the right size reusable k-cup for it. This is perfect. Cleans nicely.

These play surprisingly well for under $200 speakers. Works well with a Roku sound bar - there are several to choose from. Easy to set up and they make the sound from your flatscreen TV really pop! Worth exploring the Roku environment. Roku branded TVs are appearing everywhere and while they're not 'haut de gamme' they have a sufficiently high (4K) resolution in a 60+ inch display.

has both D3 and K2 so you dotn need to take 2 tablets only one. D3 needs K2 to be absorbed.

For the price I am pleased with the quality. I have it connected to a 4k tv and it has no trouble converting the signal and audio into 4k

The 4k photos come out well. 4K video seemed choppy and delayed. The remote and mounts are useful for group pictures.

This K&N filter is awesome! I’ve had it installed in previous vehicles and it was worth it. I recently I stalled it on my 2013 Honda Accord EX-L coupe and you can see the difference for yourself. I went from getting 31-32 mpg to 40mpg. I just installed it right before the last time I filled up. It’s not bad considering my Accord is 5 years old and just hit over 100K miles. I rarely write reviews but I had to since the difference is incredible. Don’t take my word for it... try it out for yourself.

The good (or at least the useful):This is a very nice camera in a price-to-feature sense. However, it duplicates (drops) frames at the higher data rates, even in bright daylight (it drops more in dim light). In particular, these are the actual effective frame rates I get at the ostensible values shown in the menu:4k@60 - drops 3/12, effectively around 45 fps (not exactly 1 per 4; it's an odd but consistent 1/2, 1/4, 1/6 pattern of drops)2.7k@60 - drops 2/13, effectively around 51 fps (1/6, 1/7 pattern)1080p@120 - this one is true 120fps, if the lighting is good.720p@240 - I didn't test this as much but I seem to get around 200fps in good light.The best picture quality I found comes from the 2.7k video. The dropped frames at "60fps" are a nuisance but can be worked around. 30fps works flawlessly. 4k looks fine too but isn't worth it - it is sufficiently noisy that it is not really possible to discern any practical difference between a 2.7k frame resized to 4k and a 4k source frame (for example, if lettering on a sign is not-quite-readable in a 2.7k capture, it won't be readable in a 4k capture either). In contrast, the 2.7k frames are noticeably more clear than 1080p frames (In fact a 2.7k frame resampled to 1080p looks a lot better than a still from a 1080p video).Now the bad:The battery life is abysmal; I can barely get 20-25 minutes out of a full charge from either battery that was supplied with the device, which is unacceptable for my purposes. As a workaround, I used a small (3000 mAH) power bank and a short USB cable to give it closer to a 2-hour runtime. This worked well until today when the USB outlet on the device broke, leaving me with only the miserable battery capacity. I don't think I am particularly rough with the device but I did connect and disconnect that cable a half-dozen times a day, so maybe 500 or so cycles. I don't know what a microUSB connector is rated for but that still seems like it shouldn't have broken that quickly.

I’m very happy. Install was pretty easy. Definitely a huge sound bonus! My V8 doesn’t sound like a minivan anymore. And definitely noticeable (but small) power increase. Driving experience is overall way more fun with the K&N. Its pricey but in my opinion worth it over all, I’m very satisfied.
