I like the ceramic blades, but the tool is too thin. The previous model is much better to hold. Just a shame it doesn’t last very long. They need to add the teeth from this model to the older one.

Great product

[PRM-S500Y] タジマ(TAJIMA) リール水糸蛍光イエロー細単品1個

全長245mm

Solid wrench! Extremely happy with my purchase

Arrived quickly and without issue. I haven’t been in a situation to use it at work yet, but I’m excited to try it out! You can tell by the weight and feel that it is a quality tool while still not feeling too heavy or bulky. You can tell from the shape of the jaws that it will hold firmly without slipping.

セットばらし品だがきちんと梱包されていた。

セットばらし品を購入したのは初めてだったが、きちんとダンボール箱に梱包されて届いた。ハイコーキの草刈り機で動作を確認、スマホとのブルーツース接続も確認した。耐久性などは今後。

念願の36Vマルチツール

HiKOKIの36Vマルチツールとして申し分ないスペック。スターロックマックス対応で、取り外し機構もピン無しのレバーで完結する。サイズは最初大きく感じるがパワーがあるのでこのくらいの方が扱いやすくよかった。

数量2以上でおまけミミセン1組+MisakaZooオリジナル耳栓ケース付

ありがとうございます。

早く発送していただいた上、商品・梱包ともに全く問題なく感謝しております。さらにおまけも付けて頂き…！今回、こちらの不手際で住所が正確ではなく、お手を煩わせることになってしまいましたが、その際も大変誠実にご対応頂きありがとうございます。
商品についてですが、遮音性が抜群で、工具使用時や就寝など幅広く使えると思います。個人的にはピュラフィットより遮音性が高い気がしました。ただ、その分ピュラフィットよりは若干硬めのような気もします。耳の穴が小さめの方は、ピュラフィットの方が良い場合があるかもしれません。
