Worth the work,but work all the same

I was really excited about using this method for making iced coffee. I can't stand the bitter burned taste of my brewer, but I really didn't care for the time need and messy clean up of my French press.  The good news is that this makes great tasting coffee. The bad news is that there is some trial and error involved in getting the perfect cup.
First, you have to brew reasonably fine grounds in 175 degree water. This took about 10 minutes of temp taking using my microwave and a food thermometer.  Then my grounds were too thin the first brew, so I mixed them with coarse grounds left over from my french press.
After brewing the concentrated coffee, I had a hard time calculating the right amount of milk, water and ice for ice coffee. The Makers of this product should consider having a few recipes on their site. The instructions come with instructions for making a basic coffee or a latte, but nothing iced.
Bottom line: after a few days of experimentation, this has a lot of potential for making a fantastic brew. Clean up's easy and it tastes wonderful. Just don't expect that 20 second cup of perfection that first time around.

This product worked as advertised.  BUT, I followed the instructions.......TAKE YOUR TIME AND DON'T BE IN A HURRY.  It was a simple, yet labor intensive process to do it correctly.

I like these,  but had to struggle and fiddle with them to get them to work ... Once they started to work no problems after that.

Work great, good price. Were a little warped from factory or shipping though. The actual product, defiantly worth the money though

These gave my Roomba the dreaded "open and clean the wheel cage" error on my Roomba 870.  For the first week, every 5-10min they would make my Roomba stop.  They did eventually wear in, but for me it's just not worth the hassle.  They now work just fine after they've worn down the treads a little bit and aren't binding anywhere, but for me, I'll just cough up the $30 for the genuine iRobot extractors that just work without hassle.

They work just fine, as expected, but I still had to make gap adjustments on two (out of four) of them, and one didn't fit the magnetic socket very well. Not really a reflection on the seller, but production quality control issues?

They work great. It does what it's supposed to, kinda hard to mess it up.

Does the work...again you get what you pay for....I will buy again and again as it works for me.

These are a good replacement. Design is different, but works just the same.

They work. Or at least, the ones that actually lock onto the jacks work. Manufacturing tolerance is awful. 2 stars instead of 1 because that's what you get for going bottom dollar.

These are great.  However, I did buy 4 of these and 2 of them had screw holes that did not match up so i had to get a drill to  make a hole and force it to work.  If you are little handy, it should not be a problem.

Work great on some things. Other things they don't stay stuck on though

They work - they do the job.  The delivery took quite a while though.  They are also not exactly as pictured.  They have a indent on the shaft maybe every half inch or so.  I don't know what function this serves, but it doesn't seem to effect performance.

They work, but are expensive. Alignment must be very close to exact, across a nearly 8 for Span. On the other hand, they work....

TLDR they still work but it will require some work. Details in review.

I was an early adopter of this system and at the time of purchase I'd rate this at five stars. Remote control, timers, automation through tasker scripts for Ok Google keywords, and towards the end integration with Alexa through Muzzley. I originally bought my starter kit at Home Depot.

These bulbs were awesome, then came a security patch no more third party integration with android via Tasker. Then finally the company stopped the online service and they became little more than phone controllable lights.

Periodically I'd check to see if someone had managed to find a way to control these via the internet. Eventually I bought a Phillips hue system. I tried to pawn them off on friends and co workers being honest about the limitations, but most already had a better solution implemented having been inspired by my original purchase.

Recently someone managed to get these going again. Source files TCPLightingWebInterface by bren1818

Essentially its a small footprint interface that pushes commands to the hub. The original project was made for windows however its very easily modified to work with any OS. Using this and chrome to identify the syntax of the URLs each link creates I was able to use another project HA-Bridge by bwssystems to control these lights with Alexa. They work like my hue bulbs now and have a new lease on life.

These work as described, but different than what I am used to.

They work well...get the job done and the cost is very cheap compared to others...
