Great multi tester. I am able to use it for several areas of need.

I'm really impressed with the quality of this multimeter. It works great, has a very solid feel and includes a very nice case plus accessories. Moreover, the price point makes this an incredible bargain. I am very pleased with this purchase.

Great meter. Have had it 5 years. The auto features has worked flawlessly. My 9v battery just started dying on me last time I used it. The only downfall is the fuse is built into the meter. So if you blow it and are trying to check parasitic draw its junk.

This inexpensive multimeter is a major upgrade for me, considering that I have been coping for more than 40 years with a couple of fragile 1960s vintage Radio Shack Micronta analog meters which work very well when the cables aren't broken (and they do break, often.) The Crenova multimeter has a rich feature set and solid construction. The Hold and Max functions seem very useful, the cables appear to be quite robust. I almost deducted a star for the documentation, which is presented in retro-Engrish translated from Chinese. The entertainment value doesn't quite offset the often confusing verbiage and features that are not documented. OTOH anyone who has a basic understanding of how to use a voltmeter, ohmmeter, and ammeter should have no major difficulty figuring out how to use this device right out of the package. Although it seems intuitive I am troubled by a lack of explanation on the use of the test lead storage features on the back - It's obvious that the leads slip into the vertical slots, but what is the purpose of the horizontal cuts in each lead slot? They seem the right size to perhaps be used for temporarily policing the wires to a shorter length while the meter is in use. Some mention of them or illustration in the Quick User Guide would be appreciated. Another conspicuous omission is any mention in the book of the required 9V battery (not supplied) or how to install it. Again, not a real problem for someone who has any experience with multimeters (obviously an internal power source is required,) and the battery specification is stamped into the battery cover near the conspicuous Phillips head screw. It's not rocket science, but someone with no prior knowledge might be temporarily stumped or have to seek assistance. I'm giving it a full five stars because of the good quality and excellent value for the price. I definitely recommend this product for someone who needs a good but not super high precision instrument, or one that can measure very high voltages - This one is limited to 250 Volts with protection theoretically up to 600 Volts.

I’ve had this multimeter for over a year now. It’s gotten a fair amount of use as a DIYer with my small camper and my astronomy hobby. I’ve built my own 12v astronomy gear power supply with 110v AC and 12v 100ah AGM batter with automatic switching, boost converters and various fused ports. Having a good, accurate multimeter was essential and this one fit the bill perfectly. I really like how well everything packs into the included carrying case. Also having the alligator clips as part of the set is very convenient. Additionally the wiring used in the leads is quite robust and show last a long time. One feature I didn’t think I would use much but I use all the time is the integrated stand. The only negative I can think of is the amount of time before the unit goes into sleep mode/battery save mode, it goes to sleep a little too soon for my tastes. This obviously does not impact the accuracy of the unit or the value for money of this unit, I realize I’m being nit-picky but that’s the only negative I have come across with this unit, if you can even call it a negative. I also have to applaud Crenova’s customer support. It reached out them (after the warranty period of 1 year) as I could not get the unit to measure voltage, AC or DC. They responded back very quickly asking more questions about the problem. As it turns out (I hate to admit it) it was completely user error, I had thr leads incorrectly plugged in. Regardless, customer support was very quick to respond and even refrained at making fun of me for such a rookie mistake. I’m very happy with the purchase and would recommend it to any other DIYer out there.

I am a weekend hobbyist, not an electronics professional, so I ordered with the expectation of only occasional "light" usage. This unit is replacing (finally) a very old analog multimeter that I had for decades, and I finally decided to get a digital unit but didn't want to spend hundreds for a mainstream "pro" brand. I haven't had this unit long enough to thoroughly test it, and so far I just tested voltage across the leads of a questionable LiFeP04 battery which was underperforming. It was a relief to see an exact digital reading instead of trying to interpret an approximate voltage from a needle spanning multiple scales. The display is easy to read; even easier with the backlit feature. The unit itself is fairly ruggedized and easy to grip in the hands, plus it has a kickstand feature. The unit came with not one, but two sets of leads, which seem to be of good quality. The test probes are insulated. The alligator clips already came in handy as well. The zippered case to contain everything is a bonus looks great, is easy to also grab with one hand, and offers protection to the instrument inside. I'm not sure if it's completely waterproof, but definintely splashproof. As long as this unit offers longevity, I think it offers great value for the dollar and is worthy of consideration. Finally, shipping was fast and the product arrived in perfect condition.

A good and flexible multimeter for the cost. Works great. My only complain is the alligator clamps are way too strong, they'll cut through smaller wires.

他の方が音について書いておられますが、ダイヤルを回した時に「ピー」というブザー音が鳴ります。 やや大きめの音で、音量の調節や消音ができない仕様みたいなので内部のブザーを外すことも考えましたが、 以下の方法で強引に音量を小さくしました。 【使ったもの】 ノートやチラシなどの紙 テープ プラスチック下敷き（加工しやすく固くて平べったい物ならなんでもよい） １００均で売っている隙間スポンジテープ 【手順】 ①背面の電池カバー、側面を覆うラバー材、背面カバーを外す。（ブザーがあります） ②丸めた紙をブザーの穴奥の金属板にあたるまで突っ込む。 （ブザーの金属板に圧力をかけて音量を小さくするので、紙は隙間が無いように丸める） ③ブザーの穴から上１ｍｍくらいのところで、突っ込んだ紙をカットする。 ④ブラスチック下敷きをカットしたものを、③でカットした紙の上に置き、テープで固定する。 ⑤テープの上と背面カバーに隙間スポンジテープを貼る。 ⑥背面カバーをネジで固定し、電源を入れて音量を確認する。 まだ音量が大きい時はスポンジテープを追加する。 スポンジテープをいくつも重ね、無音にすることもできましたが、導通チェックの時のために 多少音が出るようにして使っています。

明示されていない家電の電源ケーブルの極性を調べるために購入。 きっかけは、けっこう古いコードレス掃除機（N社時代のコードレスキュー隊）なのですが使い勝手がとても良く 大変気に入っていて長いこと使用していました。 ある日、何個目かのバッテリーが寿命のようで直ぐに残量が低下するようになり、いつものように近所の電気屋に 発注したところ、さすがに交換バッテリーが入手困難で諦めるしかない状況になりました。 またある日、コンセントに極性があることを知り、オーディオの音が向上するらしいとのネット記事を散見し 見て分かるコンセントプラグは全て極性合わせをして見ました。 こちらの掃除機も型が古いことが幸いしてコンセントプラグに極性が明示されていたので、すんなりと出来ました。 翌日、驚きの出来事が・・ 掃除機を充電台から外して始動すると、いつもはバッテリー残量表示が3個あるうちの1個しか点灯していなかったものが 3個とも点灯（フルチャージもどき？）。吸い込む勢いも不具合の無い時と変わらないレベルになっていました。 今のところ運転時間や吸引力には不満が無い状態で使えています（別の安全上の不具合が心配になります）。 その経験があって、僕の中で家電で出来るものは全てやりたいという、やる気スイッチが入りました。 PCやPCモニター、４KTV、BDレコーダー、オーディオ、空気清浄機に至るまで出来るものは全て極性を合わせました。 驚きの結果です・・ 極性合わせをしたあとでオーディオの音はスッキリと、４Kモニターは処理速度関連の性能上の問題と思っていたものが 応答遅れの様なチラツキがほとんど無くなり明らかな改善が見て取れました。 ちなみに極性合わせ以前からフェライトコアも電源の要所に入れていて、そちらの向上効果分がベースになっています。 気のせいの部分も有るのかも知れませんが自分の中では満足できるレベルです。 補足・・ 極性合わせが出来ない物の中で多いのは最新の家電で、メーカーに問い合わせたところ極性に左右されないように 出来ているとの回答でした。が・・ 回答をしているのはエンジニアではないため信憑性に乏しく、他の方法を探したところボディアースの電位差から 判別する方法があるのを知り、こちらの商品を購入するに至りました（前置き長くてすいません）。 AC/DC対応でμAから測定出来るので、微小な差も判別でき、不明だった最新家電も判別可能になりました。 自身の所感として、チリツモのノイズ低減効果の賜物ということで、現状で音も映像も大満足です。 特筆は・・ 目で見て分かる４K（２Kのアップコンバート）映像は今までとは全く違い明らかに良くなったので 例えるなら有機ELTVの店頭デモに近づいたかも？液晶TVなので明るさは勝っているレベルといった感じです。 大きな達成感を喜びと共に感じることが出来ました！ テスターの詳細インプレじゃなくて申し訳ありませんでした。 ご参考まで。長文すいませんでした。

なかなかの、扱いやすっく、暗いところわ、バックライトがあり、いいですね、測りも、ほぼ正確でわないかと、思います、
