I’ve had these trimmers when they first came out in the early 2000’s. I’m a barber and used them on every line up. These are similar to the wahl detailers, use these to go over the line you’ve already created for that extra detail at the end. Priceless.

This trimmer is great! Cuts sharp and crisp for a quick touch up. Totally impressed and the price is not bad compared to other sellers. Definitely would recommend!

So far -- after first use -- it does what I expected very well. It will be interesting to see how long it holds up.

The Gwhiz is great quality considering how cheap it was. Super pleased with it.

This is the second trimmers we've owned made by Wahl. The first ones we had for years, didn't look at another brand when we needed to replace them. So far, the new trimmers are just as we expected the Wahl quality to be.

Very good liner, didn't disappoint me

It's a good trimmer for being battery operated. Doesn't cut as close or good as others do. It's basically recommended for personal use. For on the go trips and such. Can be zero gapped.

I like it! After adjusting the blade it cuts really close. For it to just run off of a single AA battery, it definitely gets the job done!

I'm a consumer, not a pro, seeking a quality cordless trimmer with replaceable, adjustable blades, for both travel and everyday use. My search is over. The G Whiz trims very close, especially after zero-gapping the blade. If you don't know how to do this, see https://www.youtube.com/watch?v=7NCPJPfDWIE . The standard-width T-blade is just right for my purpose -- though it would be easy to swap it out for a Wide T if desired. One quality AA battery is good for weeks of use. I prefer high-capacity Eneloop rechargables. Finally, Barber Supply got it delivered very fast and at a very competitive price. I will not hesitate to order from them again.
