Quality item
Quality item from a respected manufacturer. Comfortable and reasonably easy to adjust. Reasonably priced. Just make sure when purchasing that you select the model with the right type of filter for your requirements.

Best temp mask ever - beats Cartridge, hands down
Shame its not sold in the USA - but worth ordering from UK as its the best carving, spraying and finishing maskVery comfortable and lasts a long time for a temporary mask, been using them for years - recommended and way more comfortable than cartridge masks - you can clean them too! - Not the filter part but that can be cleaned carefullyRecommended

seems good, but, no beards???
Not used it yet, but fast delivery, comfortable fit with soft rubber seal on face. Only concern is in the instructions leaflet it says not suitable to be worn with beards or facial hair as it may break the seal on face.

Makes using solvent/oil-based paints tolerable
I really like these masks. Over the past 6 years I've been through several and use them for all DIY tasks involving dust or fumes (for me as a DIYer they last a year or two, assuming you store them properly). When using solvent-based polyurethane, oil based paints thinned with white spirits, spray can paints etc, it completely eliminates all fume small and completely eliminates the headache I would otherwise get in a few minutes without a solvent-rated mask. It's also comfortable to use for long periods, seals well to the face, and doesn't get too much condensation inside it (although it does get some, esp. if you're using it outside in winter).

Excellent for fumes
I got this because they’re also used in the aviation industry where I work.I was suffering from mild symptoms caused by furniture wax remover, using the mask I could no longer smell the fumes and the symptoms cleared up.There’s no real smell from the mask itself and breathing is very free and easy.Simple to put on and adjust.Wipe it out after use and keep it in the dust bag.The bag it comes in is resealable but very flimsy and probably won’t last long at all.

Works well
I have a solvent allergy.I used this whilst using 'anti-bug' spray indoors. I was fine.
