    5.0 out of 5 stars Good price

    M.t.v. · 24 September 2025

    I can only assume it's good as it's not really the kind of thing you can evaluate, but this 5.1 was the same price as dot 4 so I replaced all the fluid, if I crash and die from brake failure I'll have the coroner update this review.

    5.0 out of 5 stars Perfect for Sram Dot brakes

    a. · 25 September 2025

    Bought to use with sram dot brakes, much cheaper than buying cycle branded stuff and is just the same, worked perfectly in bleeding both brakes and they are better than ever

    5.0 out of 5 stars Just what I needed!

    C. · 6 October 2025

    Perfect for what I needed☺️

    3.0 out of 5 stars Good, but certainly not worth the inflated price over their Dot4

    J.A. · 18 May 2016

    This actual product is *good*, but it isn't great, and buying it for the Dot number of 5.1 over many Dot 4 fluids is, counterintuitively, not the smart choice.The *minimum* specifications for a Dot 5.1 brake fluid is a boiling point between 190°c "wet" (meaning that the fluid has absorbed water naturally, as all glycol based fluids do) and 270°c "Dry" meaning it is new and hasn't absorbed water. When brake fluid boils it is possible to lose almost all braking ability, and when it is wet it corrodes the brake lines, so wet and boiling brake fluid is just dangerous.As brake fluid really loves and attracts water, this is an important reason to regularly change your brake fluid, and the reccomended time-scale is to test every year and replace every two years.According to Commas own specification sheet, available on it's website for anyone to view, the specs for this fluid are a boiling point wet (saturated) of 183°c and a spanking fresh and dry 275°c.Now these are adequate, but there are Dot 4 fluids out there for comparible prices that outperform the minimum specifications for Dot 5.1 fluids, and so this fluid also by a simply staggering margin.Also worth noting is that Commas own Dot 4 brake fluid is almost as good as their Dot 5.1 as the brake fluid dry boiling temperature is only 5°c lower at 270°c, and it's wet boiling point is at 160°c, 23°c lower. If you maintain and check your fluid every year to two years, there is no point spending 50% more for their barely superior Dot 5.1 fluid over the Dot 4 I *should* have bought for the price of a much better product.The minimum specs for dot 3, 4, and 5.1 are as follows"DOT3: Dry - 205 °C, Wet- 140 °CDOT4: Dry - 230 °C, Wet - 155 °CDOT 5.1: Dry - 270 °C, Wet - 190 °CCastrol SRF Dot 4 brake fluid has a WET boiling point of 270°c, and a dry boiling point well north of 300°c. Now while this example is up to four times as expensive as Commas 5.1, if you are looking for the *best* fluids for your car, (as I can only assume that you would be when looking for Dot 5.1 fluid over Dot 4 fluid) price isn't the most important factor, safety and quality is.Another, cheaper Dot 4 fluid out there has a minimum wet boiling point that exceeds this product and only cost a small amount more. Motul RBF600 with a wet boiling point of 216°c, and a dry boiling point of 318°c. Far more acceptable.My advice is to be careful when it comes to brakes and brake fluids. Just because it is advertised as better, it doesn't mean it really is worth that hike in price.
