Just FYI, there are two versions of the cordless Katsu router, a “budget” version and one which is more of a Makita clone. I accidentally bought the budget version without looking too closely at it and it was horrible. Terrible QC on the fitting and finish and no safety switch; you can easily turn it on by accident when picking it up. Returned and swapped for the proper cordless version; safety switch, 2 LED lights, significantly better QC on the finish, perfect fit for Makita LXT batteries, rack & pinion, etc.
The budget version is quieter but has quite a harsh brake that I could see causing tearing out if still in contact with the work piece.
Otherwise, I am very happy with the better cordless Katsu, ordered from aim tools eBay shop which also offered a £5 checkout voucher, the big advantage is that there are so many Katsu accessories, interchangeable with Makita accessories and a fair few 3d printable add ons if you are into that.
For newbies like me it is a great router, the convenience of being cordless, and easy to use one handed, makes me go for it way more than my Big Triton (which frankly can be quite scary sometimes).
It’s not perfect, (the fence attachment is not great, setting depth on the fixed base becomes a bother real fast, you need the plunge base for the bushings, and the clamping screws for the guide bushes are terrible and are worth replacing) but if you have Makita batteries already, the router, plunge base, and guide bushes work out cheaper than the equivalent Makita bare unit, you can then spend the rest on some decent quality bits instead.
