Very efficient, very quiet excellent quality
Left it a while before reviewing to make sure not a 5 minute wonder. For a medium sized garden, this is a no brainer. Quick delivery, easy to set up (5 minutes), battery fully charged too, so 15 minutes after delivery, you're mowing... 30 minutes after delivery, you're done. So long as you don't have the length setting too short, this will mow as quick as you can walk, seriously. Battery life is good, too - again, as long as you get the length settings right... too low, and it will happily mow, but battery life is much less. You're better off using a high setting at first, then the lower one for a second pass - depending on the size of the lawn, you'll have ample power from a single charge. One thing used to annoy me about the old corded mower with roller was mowing wet grass. An absolute no no. No problem with this one... as long as you have a 15 minute window between downpours, you can still cut the grass effectively with none of the compaction, grass tearing or gouging. Again, high setting then a lower setting... no drama. The supplied strimmer is perfectly adequate for its role, nicely adjustable, very light and powerful, a good companion to the mower (mind you, the mower does cut right to the edge anyway) The other tools in the Ryobi One range are equally good quality, but save yourself a bit of money by getting a couple of generic spare batteries. You can pick up 2 x 5A batteries for a decent price and much less than the Ryobi branded ones

Almost Perfect Battery Lawnmower
I've had this for about 3 weeks now, and have done 3 cuts, so decided to put my thoughts down. Like most I enjoy a good quality lawn, and since moving house two years ago our lawn in now about 10 metre square so ditching the old petrol push mower for the 33cm cut Ryobi made sense as I was already invested in the eco system. Pros: Lightweight and easy to maneuver Good cut depth range (25-65mm) - I use the lowest setting labelled as '1' Effective grass collection system Works with Ryobi and aftermarket batteries Quiet operation Cons: Battery life is limited (10-15 minutes) Expensive batteries Overall, the Ryobi 33cm One+ 18v lawn mower is a good choice for small to medium-sized lawns, don't even think about it for large lawns. It is lightweight and easy to maneuver, and it cuts grass evenly and effectively. The grass collection system is also effective, and the mower is relatively quiet. However, the battery life is limited, and Ryobi batteries are expensive. If you are looking for a cordless lawn mower that is affordable and easy to use, the Ryobi 33cm One+ 18v is a good option. I didn't see the major benefit for a small lawn to pay the extra for the larger cut model.

Good basic cordless lawnmower, no batteries included, good for small lawns.
If you need a cordless light lawnmower, then maybe the cordless ryobi 18v one is for you. In the box, you get the lawnmower, a grass collector, and the handle rail that needs to be assembled with four nuts. Note: This version of model DOES NOT come with any batteries. You will need either the 18v 3.3ah batteries, or the recommended 5ah batteries (18v). Again these are not included in the box. Assembly was simple, you just need to remove the packaging, check contents and build the handle. This requires four screws/nuts and is included in a paper packet. However in my box, one of the rail bolts was missing. The packet was not sealed and there was only 3 items in the packet for the upper rail assembly. Luckily these are universal bolts, so I was able to replace it myself. The build quality of the lawnmower is pretty much plastic all the way, with the exception of the handle and the motor/blade itself. Being cordless is probably its best attribute as no wires to get caught up in. You get three blade positiions as well, so you got 4 blade positions as well, so you can adjust the cutting length. You turn the unit on by engaging both handles and pressing the green button. There are no other functions beyond that. In terms of battery life, the 3.5ah battery at 18v lasts about 10 minutes and results in lower blade speed, so its not going to cut as fast as the 5ah battery which has a higher engine speed. The mower is fairly stable, easy to use and quite light. It will handle a straight lawn fairly well, but with wet edges it doesnt perform as good. This is more because of the weather during spring time. So you might still need a strimmer, even though it says you should not need one. The longer life battery at 18v (5ah) runs for much longer and seems to do a better job. Its super easy to use and has very simple controls. The grass box is also quite easy to fill and empty as well. For a basic cordless lawnmower it works on small gardens. If you want to get the best out of this mower, your going to need a minimum of two large batteries and 2 of the smaller ones. You can use the Ryobi strimmer ones too as they are universal across the range, but it simply lasts half the time and the strimmer batteries run slower. Pros: Easy to assemble, good for small lawns, works well with both types of ryobi batteries. Cons: No batteries included, could have included one to get you started.

no more mains lead
lovely mower nice and light, has a handle on top so easy to pick up, i have already got ryobi strimmer and drill, so one battery was all i needed, good size grass box also has mulching adaptor, assembly easy just handle and four bolts, good value for money, i like ryobi tools any way, no more messing around with the mains lead to cut my lawn, all four wheels ajust together, which is good, two things on the down side the ajustment handle for the wheels is a bit flimsy just becarefull when ajusting hight, and the on off button, have to press hard to get it to start, still i like it

Bis heute in regelmäßiger Nutzung. Wenn man bei der Sense die Schnur gegen klingen tauscht hat sie auch richtig Dampf. Der Rasenmäher ist nur für kleine Flächen geeignet.

TOTAL SCAM!! Product is garbage. SELLER ONLY REFUNDED $24 ON A $464 PRODUCT . I have a very small yard; grass was not wet or tall. Just to get one row in (maybe 25 feet) had to switch batteries three times ( nothing wrong with batteries). So I return it, without any damage since I couldn’t even use it, i packed it exactly how it came to me with all the same packing materials. SELLER ONLY REFUNDED $24 OF THE $464 PRODUCT I had to contact Amazon numerous times and finally they refunded me because the seller refused. TOTAL SCAM

Der RYOBI 18V ONE+ Akku-Rasenmäher OLM1833B hat mich rundum überzeugt. Die Lieferung erfolgte gut verpackt und pünktlich. Der Zusammenbau war sehr einfach und in wenigen Minuten erledigt – perfekt für alle, die keine komplizierte Montage möchten. Den ersten Einsatz musste der Mäher direkt unter schwierigen Bedingungen meistern: richtig nasses Gras. Trotz dieser Herausforderung war das Schnittergebnis sauber und gleichmäßig. Der Mäher arbeitet zuverlässig, ohne Leistungsverlust oder Verstopfung. Ich nutze den Mäher mit einem RYOBI ONE+ 18V 5Ah Akku, der ausreichend Power und eine gute Laufzeit bietet. Trotz der Kunststoffkonstruktion macht der Mäher einen sehr wertigen Eindruck und wirkt robust. Besonders gefällt mir die kompakte Bauweise und die 33 cm Schnittbreite, ideal für kleine bis mittlere Gärten. Die Handhabung ist leicht und angenehm, und dank des Akkubetriebs entfällt lästiges Kabelziehen. Ich bin sehr zufrieden und kann den RYOBI 18V ONE+ Akku-Rasenmäher uneingeschränkt empfehlen – eine klare Kaufempfehlung für alle, die einen leistungsstarken und einfach zu bedienenden Akku-Rasenmäher suchen.

Ottimo prodotto. Ha una marcia in più anche grazie al fatto che non ha fili. La batteria con un utilizzo intenso non dura molto ma il suo lavoro lo svolge egregiamente. Facile da usare anche per i meno esperti. Consiglio.
