Synthetic High Temperature Automatic Transmission Fluid provides the gear protection of a GL4 gear oil in an Automatic Transmission Fluid and provides a higher viscosity at higher operating temperatures, allowing the transmission to operate at 70 Degree Fahrenheit higher temperature and still provide the optimal shiftability and improved torque converter efficiency. The evaporation characteristics are significantly improved, being twice as good as our Synthetic Automatic Transmission Fluid and five times better than a petroleum Automatic Transmission Fluid. The improved thermal stability significantly reduces the rapid evaporation of the Automatic Transmission Fluid which can produce a frothing out the filler tube. The balanced frictional characteristics provides smooth and consistent shifts for extended drain intervals. The superior stability compared to petroleum Automatic Transmission Fluids allows high temperature operation without varnishing valves and clutches which leads to transmission failure. High Temperature Automatic Transmission Fluid is perfect for heavily loaded vehicles which see high temperatures and automatic transaxles which are benefitted by the extreme pressure protection of a GL4 gear oil to lubricate the final drive. This product can be used in manual transmissions which require Automatic Transmission Fluids and will provide much better gear protection than a petroleum Automatic Transmission Fluid; however, MTL® will provide better wear protection and better low temperature shiftability in most manual transmissions which call for an Automatic Transmission Fluid. High Temperature Automatic Transmission Fluid is suitable for use in automatic and manual transmissions and transaxles where Dexron® III, Dexron® II or Mercon® is recommended.

Solidly constructed and has a premium, hefty weight
Size: 58.5mm
Works exactly as described. Can be a bit heavy but otherwise it is a premium built product. If you have too much coffee in your basket and they're near the rim of it, coffee can get stuck to the sides of the distributor. A little annoying but easily remedied by brushing the grounds back into the basket or by "flattening" the coffee grounds in the basket first prior to distributing.

Would purchase again
Size: 58.5mm Flat Base
Fits my Gemilai portafilter perfectly. Works as expected, but can be slightly unlevel in tamping. Has a tendency to push the coffee down more on the handle side of the basket. I try to make sure I apply pressure in the middle of the tamper and it seems to make all the difference.

used product, but works
Size: 58.5mm, Size: 58.5mm
The product is good, I was sent a was clearly looks to be a used product with scuffs on it and some rust, I can clean that up and for what it does, it'll do, just weird to receive a used product.

Great scale that needs some improvements to be perfect
Color: White, Color: White
Very accurate scale, looks good in white, timer works nicely and I do like the concept of the ratio conversion. Shown in photos with 0 measurement drift over time, even without the silicone mat.
To make this the best scale in the price range, I would change:
- The auto timer function. Timing currently stops if you pick up the brew to swirl; you must completely restart the process if you do happen to pick it up. I would change that to only stop on user input (pressing a button).
- The ratio conversion. Why offer XX.0 precision if you can only change the ratio in whole amounts? I'd suggest offering 0.1 increments, selectable with +/- buttons instead of cycling through.
- The silicone mat is not well affixed and slides around. Kind of useless as-is and I just keep it off. I would wrap the whole thing around the measurement platform, similar to how the Greater Goods scale does it, to really keep it secure.
It's not perfect, but for the price, it's a 4.5/5 for me. Rounding up to 5 since a 4 is considered "bad" by today's online rating standards.

IMO, a filter coffee lovers best scale option on a budget. Solid grade A choice.
Color: Black
I have two other .1mg "coffee" or food scales that I used regular for pour overs. I saw this has 4x display on real time flow rate, g/mg weight, timer, and grounds to water ratio for a solid price and purchased this after reading some reviews. One of my scales has these features, but the workflow on this scale just clicked a ton better for me.
The beep isn't super loud annoying which is a major relief, as I just couldn't keep sound on on my other scale due to that trigger honestly. I tried brew mode immediately and will now only use that when making a pour over. Loved the beep alerting when I finally hit the proper ratio and I like it keeps my final info on screen after the brew for my study. I can actually practice my technique now and not have split attention as much.
This is still compact, but fits a larger carafe well whereas my other scale is a better fit for the espresso machine. The display is clear and buttons have a slight tactile sensation from the print, but are still the capacitive touch based style. I tested it with weights and it is my most accurate scale, it hit the .1g accurately every time or at worst would fluctuate back and forth quickly from the true value (more than enough for me to trust it). It updates and tares from power on fairly fast, it reacts fast enough to touch to not make me pause much.
My nitpicks are that the front clear matte plastic isn't quite uniform flat viewed at an off angle giving it a cheaper look, but that doesn't affect functionality at all and truth is, it really was very affordable for the feature set I feel.
The second nitpick was that the scale's mat does not grip well or fit securely over prompting it to move around easily. For this I had to modify using some rubberized grip tape on the surface of scale underneath the mat itself. Now it doesn't slide from vibration and if any pressure down it doesn't slip. I could have removed it totally, but it is attractive and useful once stabilized. With that modification done, I can fully recommend this scale for filter coffee lovers at any price. Great product, hopefully lasts me a long time.
