The specification sheet is the least useful document in the transaction. These are the questions that actually decide whether the machine earns.
You have decided to buy a laser machine. Somewhere between deciding and paying, a specification sheet arrives with a lot of numbers on it, and almost none of them will predict whether you make money with the thing.
These are the questions worth asking instead. They are written from the other side of the counter: from selling machines, training people on them, and then getting the phone call four months later.
The questions about the machine
What will it mark, and what will it not? This is the whole decision, and it is the one most often answered with a shrug. A fiber laser marks metal and hard plastics beautifully and will not touch clear glass or bare wood. Ask for a test on your material, not a demonstration on the seller's sample tile.
What is the source, and what is its rated life? The laser source is the part that eventually ends and the part that costs most to replace. A number in hours is an answer. "It lasts long" is not.
Who fixes it, and where are they? A machine imported by somebody with no service capability is a machine you own alone. Ask where the nearest person who has opened one is sitting.
What spares are held in the country? Not "can be ordered". Held. The difference between a fault fixed in two days and one that takes two months is a shelf in Nairobi.
Price per watt is the wrong number: power is the easiest figure to compare and one of the least important. A well-supported 20W machine that runs every day beats a 50W bargain that has been waiting five weeks for a part.
The questions about the seller
Is it tested before it ships? A machine that is switched on, run, and checked before it leaves is a different proposition from a sealed box passed straight from a container. Ask to see the test.
What training comes with it, and how long? Not a video. Somebody sitting with you until you can set a job, focus the beam, choose settings for a new material and diagnose a bad mark. Training is what turns a machine into a business, and it is why it comes with a machine purchase here instead of being sold separately.
What happens in month three? The first month is exciting and the third is when the real questions arrive: a material that will not mark evenly, a customer wanting something you have not tried. Ask who answers that call.
Can you talk to somebody who bought one? A seller who cannot put you in touch with an existing customer is telling you something.
Which machine, roughly
Without turning this into a price list (that is covered properly here), the shape of the decision is simple.
A handheld fiber marking machine (30W, KSh 290,000, in stock) is the workhorse for metal: asset tags, cutlery, tools, rims, ear tags. It is portable, which means the work can come to you or you can go to it, and mobility is what makes on-site jobs possible at all.
A handheld metal marker sits below it, at KSh 160,000 with a 10 to 14 day lead time, for someone whose work is narrower and who wants to start earning before committing further.
Bigger cutting and desktop machines are a different business again, with different floor space, power and extraction requirements. If the plan is a mobile service, do not buy a machine that needs a room.
Ask about the safety class too. Lasers are classed internationally from Class 1, which is safe under all conditions of normal use, up to Class 4, the highest and most dangerous. Many powerful lasers count as Class 1 only because the beam is fully contained inside an enclosure. An open-beam marker of similar power falls in a higher class, with the precautions that come with it, so the class decides where the machine can safely run.
The cost that is not the purchase price
A machine is bought once and run for years, and the running side is where budgets go wrong. Consumables are modest on a fiber marker: a protective lens window that is replaced when it clouds, and very little else. They are not nothing, though, and a lens is exactly the part people run past its useful life, because the machine still works, just worse, and the decline is gradual enough to miss.
Then there is the cost of not being able to work. A machine down for a week during a school-tagging season is not a repair bill, it is a lost season. That is why the service question above matters more than the specification: the arithmetic of ownership is dominated by uptime, and uptime is a function of who you bought from.
Before you pay
Three things, all of which are ordinary and all of which get skipped in the excitement: see the machine you are buying switched on and marking your material. Get the training dates in writing, not the promise of training. And find out what the machine is worth in 18 months, because a machine nobody else in the country supports has no second-hand value at all.
Planning a service business? Look at the jobs that get asked for before choosing the machine. The work decides the machine, not the other way round.

Common questions
Do I need special power or a dedicated room?
Handheld marking machines run on ordinary single-phase mains and need a bench, ventilation and sensible extraction for fumes. Larger cutting machines are a different matter: floor space, extraction ducting and in some cases three-phase power. Decide what work you are doing before you decide what you can house.
How long does it take to learn?
Producing a clean mark on a familiar material takes a day. Being able to walk into an unfamiliar job, choose settings, and be confident in the result takes a few weeks of doing it. The gap between those two is where most new owners lose money, which is why training comes bundled with the machine, not sold as an extra.
Can a laser machine mark anything?
No, and any seller who says otherwise is worth walking away from. Each laser type has materials it handles well and materials it cannot touch. Fiber is for metals and many plastics; UV covers heat-sensitive surfaces and glass; CO2 handles wood, acrylic and leather. Match the machine to your actual work.
Do you deliver machines outside Kenya?
Yes. Machines are tested before they leave and have been shipped across East Africa and further afield, with the training included regardless of where the buyer is. Delivery, within Kenya or abroad, is charged at what it costs and written on the quote before you commit.
