Description

Voltage Regulator | Mk4 | B5 | Mk1 TTThe voltage regulator maintains a constant voltage level by controlling the output of the alternator. If you're alternator is failing to charge your battery or run the electrical systems of your vehicle, the internal diodes of the regulator may be faulty. A good way to check for a faulty voltage regulator is to use a digital multimeter on the battery, with the engine running, to read the charging voltage. If voltage is not constant around 13 to 14

The voltage regulator maintains a constant voltage level by controlling the output of the alternator. If you're alternator is failing to charge your battery or run the electrical systems of your vehicle, the internal diodes of the regulator may be faulty. A good way to check for a faulty voltage regulator is to use a digital multimeter on the battery, with the engine running, to read the charging voltage. If voltage is not constant around 13 to 14 volts, chances are the voltage regulator has gone out. Replace yours to restore proper operation to your charging system.

Very soft and the matching backing is nice
The blanket is great quality with no smells. It’s thick and cozy. We like the matching backing. Unfortunately, I should have measured because this barely covers a queen bed despite the heading product description “queen size”. I still haven’t heard back whether they use harsh chemicals when processing. Overall, it feels great to support companies that use natural products with (hopefully) low to no harmful chemicals.

Great for blankets
Great for making sherpa or fur blankets soft again after wash. I imagine it'll work well for fur hoods as well. It did a good job of removing lose hair fibers and the quality is good, even if it's extra spikey. Overall, affordable solution and good looking brush to rejuvenate faux fur

Great but Pain
It’s alright, does the job as it is supposed to. It’s easy to use and helped fix my Uniqlo jacket that was all matted. It didn't restore it to it's original form however it did unmat it. If I bought this way before and touched up the jacket, I think it would of been perfect to this day still. Maintenance of those jackets are a must! The brush is strong and works well for fluffing it up because of the metal wiring. The only bad parts are that it can hurt if you accidentally poke or scratch yourself, I actually got cut by it when I quickly was brushing. It’s kind of hard to get the lint off the brush but it's better than others and might hurt because of the metal. But overall, it’s a cool tool that makes my jacket fluff again!

Works well, however…
Purchased this to give life back to my Sherpa backed blankets. This is a well made brush handle is comfortable. The teeth are strong and durable. They did not bend around while I used it and maintained its shape. The problem I guess I’m seeing is that it doesn’t get deep down into the fabric to it’s just a surface “petting”. Maybe if the teeth were further apart or something. But does seem to provide some form of fluff.
